Couple of things....

You stated that in your previous game where you were on the bases, you noticed the pitcher's foot lifting, but ultimately decided not to make any call. No problem, your judgement.

As a general rule of thumb, most actions with the pitchers feet are the call of the BU. The PU has too much other stuff (such as the pitch) to watch as well as having a bad angle on the pitcher's feet.

On your plate game, when the coach came out, I would have directed her to the BU for that game, Evidently, your BU made the judgement that the pitcher was not illegal in that game since you don't mention any illegal pitch calls in your post.

By telling the coach that her complaint may have been legitimate in the first inning, but not the eighth, you have sent the message that you know the pitcher is illegal, but you are choosing to ignore it because you now have a close game in the eighth inning.

If you do need to respond to the coach, a better repsonse may be: Coach, I have watched the pitcher throughout this game, and in my judgement, she is legal.
