I think if I hit a HR within 5 beats of my MHR in a race for longer than 15 seconds the field would get away.

That is exactly the point. Her max measured HR so far is 175. She may not be able to get there via the bicycle YET, but it is the ability of her heart to beat. Therefore, if she were using HR training zones based on max HR, should she use 175 for her max or even a high number? I do not know and I suspect others do not know either.
