SUMMARY ORDER

Opal Financial Group, Inc. (“OFG”) appeals from a judgment entered after a three-day bench trial on an action brought for trademark infringement in violation of the Lanham Act, 15 U.S.C. § 1051, et seq., and unfair competition under Connecticut common law. Before the District Court, OFG sought injunctive and monetary relief from Opalesque, Ltd. (“Opalesque”) and Matthias Knab (“Knab”), who denied any liability to the Plaintiff and asserted a counterclaim under the Connecticut Unfair Trade Practices Act, Conn. Gen.Stat. § 42-110b, et seq.

OFG brought its trademark infringement claim pursuant to the Lanham Trademark Act, whose principal provisions are found in § 32(1), 15 U.S.C. § 1114(1), and § 43(a), 15 U.S.C. § 1125(a). In our Circuit, a claim of trademark infringement “is analyzed under the familiar two-prong test,” which “looks first to whether the plaintiffs mark is entitled to protection, and second to whether defendant’s use of the mark is likely to cause consumers confusion as to the origin or sponsorship of the defendant’s goods.” Virgin Enters. Ltd. v. Nawab, 335 F.3d 141, 146 (2d Cir. 2003) (citations omitted).

“[T]he crucial issue in an action for trademark infringement or unfair competition is whether there is any likelihood that an appreciable number of ordinarily prudent purchasers are likely to be misled, or indeed simply confused, as to the source of the goods in question.” Mushroom Makers, Inc. v. R.G. Barry Corp., 580 F.2d 44, 47 (2d Cir. 1978) (per curiam), cert. denied, 439 U.S. 1116, 99 S.Ct. 1022, 59 L.Ed.2d 75 (1979). In evaluating whether a trademark owner claiming infringement has satisfied its burden of showing a likelihood of consumer confusion, courts in this Circuit routinely apply the non-exclusive multi-factor analysis developed by Judge Friendly in Polaroid Corp. v. Polarad Electronics Corp., 287 F.2d 492 (2d Cir. 1961). See Arrow Fastener Co., Inc. v. Stanley Works, 59 F.3d 384, 391 (2d Cir. 1995), These factors, include the following: (1) the strength of the mark, (2) the similarity of the two marks, (3) the proximity of the products, (4) actual confusion, (5) the likelihood of plaintiffs bridging the gap, (6) defendant’s good faith in adopting its mark, (7) the quality of defendant’s products, and (8) the sophistication of the consumers. See, e.g., Louis Vuitton Malletier v. Dooney & Bourke, Inc., 454 F.3d 108, 116 (2d Cir. 2006) (listing the Polaroid factors).1

OFG first argues that the District Court erred in its treatment of OFG’s admission within its summary judgment papers that it had never offered professional continuing education credits in connection with its conferences. The District Court deemed *28that admission binding at trial, notwithstanding conflicting testimony from OFG’s CEO. In OFG’s view, that was erroneous under Federal Rule of Civil Procedure 56(g). We need not and do not decide this issue because any such error would have been harmless. Insofar as OFG argues that the District Court’s alleged error as to the availability of professional credit at OFG’s conferences was material, it argues that the error led the District Court incorrectly to find that OFG’s products were not proximate to Opalesque’s. But as we next conclude in analyzing OFG’s argument that the District Court erred in its Polaroid analysis, the record supports the District Court’s finding of minimal proximity between the products regardless of whether OFG’s conferences offered professional credits.

OFG argues that the District Court clearly erred in its separate determinations regarding each of the eight Polaroid factors, particularly “the proximity of services and marks and the evidence of actual confusion as embodied in the survey results.” Appellant’s Br. 16. On the issue of proximity, the District Court found that the parties offered different services solely because OFG’s “principal service” was “organizing and producing networking conferences of several days’ duration at resorts,” whereas Opalesque’s “principal services” were “online newsletters and brief online webinars sans networking.” Special App’x 44-45 (emphasis omitted). In our view, the District Court placed too much emphasis on that fact. It is true that the parties’ principal services differ, and that. Opalesque’s allegedly infringing educational events amounted to a small, short-lived business. But, although the proportion of a defendant’s product line that allegedly infringes the plaintiffs products may be relevant to a court’s proximity analysis, see, e.g., Nikon Inc. v. Ikon Corp., 987 F.2d 91, 95 (2d Cir. 1993), the fact that Opalesque’s allegedly infringing products are not its “principal service” cannot, on its own, establish a lack of proximity. To the extent that the District Court’s decision suggests otherwise, we disagree.

Nevertheless, additional evidence in the record supports the District Court’s conclusion that the parties’ products differed substantially. Regarding the Global Alpha Forum—the allegedly infringing product that most closely resembled OFG’s conferences—the District Court found (not erroneously) that Opalesque served as a media partner rather than a conference producer, which distinguishes its service from OFG’s.2 As for the Yale Club workshops and webinars, those events differed from OFG’s conferences in several significant respects, regardless of whether OFG offered professional continuing education credits. The workshops and webinars had *29notably shorter durations and smaller sizes, took place at non-resort locations, and lacked sponsors and media partners. In light of these distinctions, we conclude that the District Court’s finding of minimal proximity between the parties’ products was not clearly erroneous.

We also conclude that the District Court’s separate determinations regarding the remaining Polaroid factors were not clearly erroneous. OFG does not dispute the court’s basic findings regarding three of the factors—the strength of the plaintiffs mark, the similarity of the two marks, and the quality of defendants’ products— and we conclude that those findings were not clearly erroneous.3 OFG does, however, contest the court’s findings that the final four factors—consumer sophistication, actual confusion, the plaintiffs likelihood of bridging the gap, and the defendant’s good faith—favored the Defendants, In our view, none of those findings was clearly erroneous, either. Evidence in the record suggests that the consumers in question were indeed sophisticated, and OFG offered little evidence that consumers were actually confused,4 that it planned to bridge the gap and compete with Opalesque’s distinct types of educational events, or that Opalesque either adopted or used its mark in bad faith.

*30OFG argues further that the District Court improperly balanced its determinations regarding each Polaroid factor to conclude that there was no likelihood of confusion. We disagree. The District Court did accord special weight to actual confusion, the proximity of the products, and consumer sophistication, but it also considered the remaining factors. That approach was sound in the circumstances of this case, as was the court’s ultimate conclusion that OFG “failed to sustain its burden of proving that a likelihood of consumer confusion exists with respect to the trademarks used by the parties.” Special App’x 47-48. Although the trial may not have been perfectly executed in every respect, perfection is not the standard. The District Court’s alleged errors do not— either separately or collectively—cast any serious doubt on its ultimate holding. Rather than claiming that the District Court erroneously ignored or misinterpreted its evidence, most of OFG’s arguments on appeal challenge the admission or probative value of Opalesque’s evidence—but OFG instigated the lawsuit and had the burden of proving its claim. None of the alleged errors overcomes the fact that OFG simply failed to provide sufficient evidence to show that “there is any likelihood that an appreciable number of ordinarily prudent purchasers are likely to be misled, or indeed simply confused, as to the source of the goods in question.” Mushroom Makers, 580 F.2d at 47.

We have considered all of OFG’s remaining arguments and find them to be without merit. For the foregoing reasons, we AFFIRM the judgment of the District Court.
