imagenet pretrained model in Model Zoo

Hi, we're trying to load the imagenet pretrained model and inflate it to the slowonly backbone. We noticed the top1 and top5 err listed there are 23.6% and 6.8%, which doesn't look quite normal - we're wondering that, is that the error rate or the accuracy rate? and how's that calculated, did you test the average over all frames within a video, or use the inflated 3d version as a fixed backbone, and evaluate on top?
Thanks so much!
