Since it uses difficulty, replace my avg target should be the harmonic mean. I was remembering wrong when I wrote N=2 Plug in N=3 and you should then see the...

N is the mean lifetime = ML in e^(-t/ML). The best alternate description might be calling it a filtering constant as jonathan toomim found [this paper](http://www.tsdconseil.fr/tutos/tuto-iir1-en.pdf) that shows EMA is...

Using e^x = 1/e^-x = 1/(1-x) for small x gives one of the alternate EMA formulas. Then multiplying by N/N and T/T gives me: difficulty = avg_difficulty * N *...

In my "perfect" grin above, the x in the above is often not small, so I'm not at all sure the "perfected Grin" is good. Half-life is easier for people...

Yes, if you're averaging 60 blocks and "lifetime" units are in blocks as opposed to seconds. The equivalent std devs are with constant hashrate. I have a theory that the...

WTEMA is going to be better in all respects because grin is partially SMA. To make DA's work better and prevent exploits, make FTL < block_time (at least no more...

@dii14 ASERT/NEFDA is going to be used for BCH. It emits too many or too few blocks if hashrate consistently increases or decreases. The excess blocks it emits is M...

This is the derivation of how the nBits truncation error E (as a fraction of nBits) will cause relative ASERT to have an avg solvetime error that is E *...

People forget that ASERT gets behind in the number of blocks if hashrate continually increases because it has perfect solvetime if hashrate is oscillating around some average. Getting behind is...

## Niobio Problem Niobio was the first coin with a correct LWMA that had a hash attack problem. The 20x miner was not getting blocks at a lower difficulty than...
