My interpretation is that people often get confused by the (not matching target) numbers shown on screen after a shorter interval or in the interval summary.
With smooth pedaling and small front ring I usually get close to those short interval targets with the Neo if I look them up on the web page, zoom in and shift those 5, 10 or 15 second block 1-2 seconds to the right. So not 1:00-1:10 but 1:02-1:12 for example.
There is a feature request to do that automatically and look some seconds around for each short interval and use the part with the highest average power for that interval duration and show that in the interval summary list. You might want to comment and upvote here:
