I find the same thing. Around 12/13 is about the mark for me.

My threshold doesn't seem to have changed since the pump.
I tested it the other day because I turned off the pump in preparation for
gonig swimming 30 mins. before, and then got delayed by 30 mins. I forgot I
had switched off the pump, and when I arrived at the pool my BG was 13.
After half an hour of swimming it was 6 mmol/l.
But, the pump may help in that you may not have to raise your Bg so high
At the JDF conference, in the exercise workshop, the marathon runner (whose
name I forget) told us how he had to get his BG up to 15 before running, in
order to finish at about 5mmol/l.Which is what I too had to do on MDI,
necause of the amount of long-acting insulin in my body.
Now I can usually start exercising around 7 and finish at 5 by careful
control of the pump.
