It has been a while since I have had the time to do any development with scrypt and after starting my Mincoin wallet again recently, I began to monitor the "SetBestChain" notifications in my debug.log.
If you care to follow along, look at height 595171 through 595199 for an example of our retargeting algorithm ineffeciencies.
During this period, the difficulty remained above 5 but afterwards, momentarily dropped to 2 and then multi-pools came along as can be seen from height 595498 to present.
This is pretty much what Mincoin looked like in April of 2014 when I had last commented on the promise of one minute blocks with SnowLeopard in #Mincoin on Freenode.
When the blocks are several hours between, the loyal miners are not rewarded.
When the difficulty algorithm finally retargets reasonably, the multi-pool miners take the money and run.

This year, Kimoto's Gravity Well has been adapted to deal with the Time Warp vulnerability which has been used to attack various scrypt chains.
I would like to collaborate with other interested developers on the Testnet to evaluate a fork of our repository with KGW enhancements for the benefit of the greater Mincoin community.
