My ascent of 'Hips Don't Lie Sit' [fb 8B+/V14] took me longer than expected:
In early spring I tried the standstart for the first time and had a promising first session. A week later I tried it again and made a solid ascent. Therefore I thought it wouldn't be a big deal to add four moves which are around fb7C (in my opinion).
It turned out to be different! I don't know how many days I spent there overall. But I know that the last hard move to the undercling incut crimp was way harder from the ground than from the stand. I fell there over and over again. Maybe if you have a better endurance than I do, it doesn't feel too different. But I needed a lucky punch to link all the moves together.
