I don't think they will work on 200%
I've tried to set it to 10000, but It gives me 100% only.
I've played to day 7, and it has only 100%, never saw 200% groove
(may be get this skill in late game)

it stands for upRate, it is 1 originally, I've changed it to 100
When you get 1 point, it will up scale to 100 times, which will reach the upper limit(100%) immediately.
So, if you change it to 200, it is no use, you will get the same result.

you may try to set it as a larger number, I've not tried it, it may work probably. Since it just modify the content in memory like the code made by
