Adaptive Training Closed Beta Update

I did my Ramp test a week ago and got 290 which was 2 watts down on my manually set ftp of 292 (I’ve been avoiding ramp test but my guess work has been fairly accurate) . So I’m unsure of why the Progression levels gave me such a high tough score. Just out of interest I manually bumped up my ftp by only 1 watt to 291 and the PL has dropped a fair bit. Doesn’t really make sense to me.
