API Update frequency - General Concern
Algorithms that are highly cyclical in nature seem to present the problem that even though the pool API is reporting a high level of profitability, drilling down into the algorithm detail shows a much different level.  This can be confirmed by the much higher level of difficulty displayed by the miner.  

Can the interval of API polling be decreased (sped up)?

Is it the stance of the developers here that the Accuracy statistic should take care of this discrepancy?

If the cycle of profitability (low difficulty) lasts 5-10 minutes, and the API (or MPM) is 2-3 minutes slow to discover the spike in difficulty, the Algorithm probably isn't worth mining.  But if everything were dialed in, it would definitely be worth it.

Is there a significant difference that anyone has found in the speed with which various pools update information available via their API?
