Why not just use FTP Academy credits???

Until you can get rakeback? I'm working on a challenge with 350 available credits. For the most part I just have to play as I normally do. Since it's part of a lesson for improving the middle levels of my SNG game there are things I needed to work on but...

This stuff's available even at the bottom. Rakeback would be tiny at the bottom. It easily takes over a week for me to earn the same number of points as credits earned in a single SNG. If you have a steady amount of money these credits could really pile up.

There are more advanced challenges where you can win 600 - 750 credits. Some of the tasks aren't that hard even in those(I said some).

Since you can reactivate challenges and save up the credits...

Why not just keep reactivating at least until you master a challenge, even beyond?

Trade 100k credits(not impossible for someone who plays regularly for hours on end) for $600. Lather, rinse, repeat. Would take awhile, but it's just one little add-on to what you're already doing.

Better than nothing right?

But then I'm probably missing something as usual.
