Hmmm, Dutchpool may be messing up. It's been almost 7 hours since last block and we have most of the Nethash, or so it says.
ALN is currently see-sawing between a 'reasonable' difficulty and a +400% adjustment. If the nethash stats you're referring to are grabbed from the client (eg via 'getmininginfo' or 'getnetworkhashps') then the calculation includes blocks mined at the lower
hashratedifficulty, so the result is not accurate.
1. Low difficulty? Butter up your ass, here come the multipools!
2. Difficulty jumps by 4 times? Multipools abruptly leave the remaining loyal miners to tough it out until the next adjustment.
3. After much longer than usual, difficulty adjusts back down to normal level. Butter up your ass, here come the multipools! etc etc
Dev asked above about fundamental changes, #1 would be a per-block retarget. It's not hard, and could have been done months ago.
