Hard to say since we have very small samples. However, it took around 50 SB to max my GPU. I farmed some more for another one and it took me 10 books to max him from level 1 (I had farmed 20 - feels bad to feed GPU SB to some random units). And it was after Ace event...

But if we compare to japan, they already have a better rate outside skill up events and they currently hav a skillup x 3 event. From what I've read on reddit, the result is around 1 skillup per 2 SB. Almost too much...
