On a trackday...........

I don't think that the question should be "is it best?", start in the slow group and if you feel like you are lots faster than the others, and would benefit from having faster riders to learn from, just ask if its possible to be put into the next group up. Theres bound to be someone in that group that's getting in the way of everyone and would benefit from being in a slower group.
