I’m new and have two horses.
On the training summary page, Horse A shows E/F of C/B. On the training workouts page, he shows A/B.
Horse B shows A/B on the summary page, and A/A on the workouts page.
Why are they different and which one do I trust?
Thanks!
There’s always a little bit of variation between all three. 
I’ve gotten A/A and B/C before in quick succession. I wouldn’t worry about it; if your horse consistently shows “A/A” or “A/B,” then he’s great. 
The best gauge to knowing how your horse is doing, energy-wise, is to give him at least seven to ten days between races, and to ship him home every two to three races (I ship my ponies home every three, depending on where they are in the world and how soon I’d like them to be able to race again). Also, read the F.A.Q. and Newbie Guides on training just to be sure your horse doesn’t get over-exercised.
Welcome to the game!
The discrepancy is meant to represent human error. You’re relying on a virtual trainer/staff member to tell you how energetic/fit they think the horse is, and people aren’t going to be 100% accurate. So there’s a variation (of up to a letter, basically) on what gets displayed.
i dont know if its happening to anyone else but my energy page wont refresh it just stays blank, no error message or anything
