Alexander Kolbasov commented on SENTRY-1773:
--------------------------------------------

I agree that leaving a single entry is not the best idea. On the other hand I'd rather avoid storing any state from NN. Can we choose value X that is good enough in practice? It doesn't have to be ideal, just practically good enough. How many deltas can be generated in 1/2 seconds? The value of X could be a few times bigger than that.

> The delta cleaner removes deltas thus causing NN full update unnecessary. 
> I think it should keep more then 1 delta.
