PW, can you present a "short term" profitability? Not a day long, but like 2 hours? That a site like http://149.5.241.57/?scrypt=&nscrypt=&x11=4400&x13=3200 can use to estimate profitability of an algorithm, based on our own speed for different algorithms?

Someone has been asking for this to my email as well.

Essentially, a 2hr block of profitability really isn't useful. Any spot profitability really isn't useful.

The biggest problem is that profitability is really only valid for a few seconds most of the time. And that profitability is rarely what you actually get. Most coins change difficulty every block, and so when difficulty drops a coin, the next block becomes reasonably profitable. But since everyone else (other multipools mostly) see that same change, everyone tends to jump on that new block. With everyone jumping on it, the hashrate increases, and the average block time drops from (normally ~60s) to down to like 10s. Making the likelyhood that we find the block lower. So while the pool is going to claim that the profitability is high, that profitability is only an expected profitability (much of the time, the realized earnings are 0), and it is typically only over a few seconds.

That would be the problem with displaying (essentially) real-time profitability. It is wildly inaccurate.

If we instead showed realized profitability, 2 hours is way too short to give an accurate estimate, and the vast majority of the time, that estimate is going to be either 50%, or 200% (vs LTC), which again, isn't really a useful stat to base any sort of decision process on.

For example, below is a graph I have in the admin section, it shows perMHs (vsLTC) on 1hr intervals. While they're not 2hr intervals, and you'd increase smoothing a bit, individual points on this graph are pretty much useless to base any decisions on. The only reason I have it on the admin section is so I can see longer trends, and general (over multiple days) corrolations.

Publishing any point on that graph is just asking for trouble from my perspective. I already get enough emails (5-10?) every day between 00:00:00 and like 02:00:00 from people being like "WTF PROFIT FOR TODAY IS 10% WTF!"
