It's fine for the highest tier. The main question is whether or not it is necessary. I guess mostly to reduce the number of less serious applications.
My sugestion was to let the different tiers have different costand requirements. It makes sense as it also takes more time to vet and review larger and more complex businesses.
I think it is way too high, especially as people asking for delegation may not have very much SBD in the first place.
Paying to apply for anything sucks. 100, 65, or 40 SBD you have just priced many people out of the market.
