I gotta ask, what is that significant slow down on the eccentric 1" off your chest? I think your two options are stay the course (meaning stick with your plan of chasing solid singles) or even doing a few extra singles with 250-260 next week. I, too, think you're good for 275 based on that bar speed but would have felt more comfortable making that statement knowing you had done something like 245-250 for a triple very recently. But we're all different, and that bar speed looked easy, so I say you should at least get 275. Form looks good, but just work on confidence and speeding up that eccentric without losing control of course.
