Just had a call with (he's part of the Practice Room Pro hence the call), he had some feedback regarding the challenges. He felt a bit overwhelmed with weekly ones since he really wanted to do each one. I explained that it's very much optional and not every challenge is going to be appealing to everyone.
The point of the challenges is to get you to learn/try something you wouldn't have done otherwise.
No pressure or comparison to anyone else.
With that said I told him I'd do a poll to see what frequency you all prefer. The last thing I want to do here is to overwhelm anyone so your input is super valuable.
(Evgenni didn't mind me mentioning him here so I'm not trying to out anyone)
