How often does a trainer have FOUR horses in a field and 2 of them are grand circuit horses??
As to the other question, I have absolutely no issue with Belinda being the official trainer. The reality is that any trainer has a team of people working the horses, planning their preps etc. Its not one person who does everything.
No different to many other training regimes - eg. Maree/John Caldow, Greg/Skye Bond, Emma Stewart/Tonkin
