Really? I sent this because I thought it would convey that I didn't know what I was doing Not that doing things right is bad, but I'm not really sure where I could go from here I could plug -15 in for dx/dt, since we know that rate, but I would need values for x and y, and I don't know how I would get those Related rat...

So if I use 7 lanes for example, each lane would have a theoretical value of winning of 1/7. But I can compare the actual values for each lane with a G-test? Or a chisquare test? I just want to make sure I understood you correctly.
