what about these spikes that go from 70k (while the pool claims 76 lmao) to 900K? Can you fix the hps math before anything else?
Because spots adjusts so quickly, some of the hash rate and difficulty figures seem, well, spotty.
It would appear that most of these issues are present in other coins, it's just not as noticeable that the figures returned for certain request methods are different across two blocks when it's something like every two thousand some-odd blocks with a coin like BitCoin. Very few people ever notice.
If you're not aware no wallet or client gives an accurate network hash rate, this is impossible.
By the same token, no pool can give you a truly accurate figure for the hash rate of it's miners.
Sometimes when the pool uses one estimation formula, and the client uses another, it looks odd. In both cases they're only estimates, based on past results and averaged out statistical figures.
And they'll both become radically inaccurate if someone comes across a couple of lucky shares or blocks. Or if there's a particularly difficult streak.
Also an extra 800k spike in hash rate is typical when one of the hopping pools hits a coin.
All you need to calculate profitability of the coin is its difficulty and the bid price on the exchange. Nobody should care about network hashrate or pool hash rate: just solo mine this coin when difficulty is low.
Pools and other websites are just inaccurate due to the bug (or a feature) inside the client (it is present as you said in other coin's clients as well): GetDifficulty and getmininginfo commands return data about the block which is already found and not about the block which currently mined (one block behind is too long for this coin). This bug will be fixed eventually or just smarter pools will start getting difficulty from "target" difficulty instead of "getdifficulty" command. So, I say: enjoy while it last: People in the know are already mining this coin when actual target difficulty is low and not based on the coinchoose data.
Edit: you can see actual difficulty from your cgminer: 100k for example = 1.52 (100k/65536=1.52)
Edit2: network difficulty is calculated based on the frequency of the submitted blocks at the given difficulty, so it is very inaccurate for Spots within small number of blocks.
