Is this a mistake?

Just reading through my up and coming training sessions suddenly we jump from .9 to .99 IF.

I am doing an lv IM plan using plan builder and looking at this session it looks hard but it doesn’t look .99 hard. Any thoughts?

It’s .99 on the website, and in this guy’s ride. It looks like essentially Mills, but with 140% peaks instead of 120%. I buy .99, 18 minutes over 120% with almost 7 at 140% seems pretty wild.

Think its to do with the 30s rolling window for the NP calculation, it doesn’t play well with short intervals.
