I don't think there are any 0.025 deductions. There are some that are "up to 0.05" (like flexed feet) so a judge might take 0.025, but they would probably just take 0.05. Most scores like "9.125" are because they average the 2 judges scores; the first judge probably gave a 9.1 and the second a 9.15, so it averages out to a 9.125.
So I'm pretty sure there really aren't any .025 deductions, but someone please feel free to correct me if I'm wrong!
