Come on Mittens back it back down again. Maxwell I think gave a couple iffy numbers in the beginning of his trial too but he always dropped back on his own. Mittens could have got excited by something like a bird outside the window or a squirrel and popped up a bit.
If he fails you'll catch it before he gets out of control and just start him back at that .25u and give him a little more support until he's ready to try it again. No harm, no foul in trying an OTJ trial.
