The power numbers indicate that Jillian no longer has a physical advantage that she once had when she was  biologically a man.  This leaves perhaps mental conditioning obtained in years of men's racing (which is typically deeper in terms of numbers of competitive athletes).  This would be similar to for example pro female coming from Europe to compete in the local series. It elevates the games. People will of course complain, but it can also be good as it pushes everyone to new levels. (Up to about 30% of elite athlete performance is mental). What the sporting bodies want to ensure is that Jillian does not have a physical advantage, which seems to be the case.
