Hi Kate,
Logically, I’d expect a bigger number of bars to be less useful for an MOC system. Personally, I’d have no issue with using 2 to (maybe) 5 bars and wouldn’t consider it curve fitting. However, if there was a patch of bars, say from 10 to 12, that gave great results, I’d have significant misgivings using any of them…why would what happened almost 2 weeks ago be relevant for a system that holds positions on average for a few hours?
My 2c for what it’s worth.
