Not sure how you are getting that but if you are using SS blocks with long rides you might want to adjust your ride feel down so the workout is easier. I could not get what you are. I agree that would be ugly. I know a guy that can ride sweet spot all day long but that is very abnormal. See what I get below
When it gets to block 18 it gets impossibly hard unless you tweak the ride feel down to easiest level.
