At the time I hade no test quantity but I thought of - a very primitive - one now, which is simply the mean of the number for n-1 and n+1, i.e. $TQ=(A056295(n-1)+ A056295(n+1))/2$ with which I compare A056295(n) I find that there is a perfect correlation between A056295(n)/TQ and the number of factors of 2^n-1 up to n=10. That is good beginning. I can't show you the graph but it is simple enough to establish.
