EQMOD questions - by: ElevatedG

I'm fairly new to AP and INDI as well with just a few questions...

How does PEC training in EQMOD work? I've tried to enable training but without any result. Also, will it help smooth out guiding? Guiding error is averaging 0.5" per night.

Also, is there a how-to for setting horizon limits correctly?

I'm using the Sky-Watcher EQ6-R Pro mount

Thanks for the help guys!
