Update:
Ok I am able to "cheat" my previous limits, and select a higher setting on OCT app that previously would freeze Sense after a while..
My limit was 748 with 768 Sense freeze after a while, regardless whether on Netripp or iwfratz apps, but..
If you select OCT app to autoscale, it does not use the highest setting long enough for Sense to freeze.
I have it now set higher at 768, with "#Steps" just at 1, and polling at 2000.
so I effectively have it running faster than I could on Netripp
