Chin ups in a Tuck

I made the mistake of not setting a time limit:



Rules should be:

1. As many as possible in a minute
2.  Chin all the way over or it doesn't count.
3. Don't drop the block (encourages control on the way down) or it doesn't count (including the last one).

If allowed to do those ugly kippy type of chin-ups (and yes, I call overgrip chin-ups and undergrip as pull ups), she can probably do double the number of reps she hit here.
