Talk Fantasy Football

The rules say that you can perform a number of Shove challenges up to half player's Jog (rounded up).
My question is: what Jog value must be halved to count how many Shove challenges you can perform after standing up from Down position?
The standard full player's Jog OR the modified player's Jog, i.e. [Jog - (5 - Grit attribute)] AFTER standing up?

Ooh, an elfball question! It's unmodified jog.

Thanks a lot!
Yesterday I downloaded your nice Vassal mod client and solo-played a bit in order to learn the rules (sadly, no tabletop players where I live ).
Thanks for your amazing work!

No probs, but brownrob and grumpy grizzly did all the work, I just zipped it up! Must make that clearer
