And do you think a 12 fold growth (from a low percentage to high) in a few days is normal organic growth?
I confirm, it is obviously abnormal even... a bit mysterious and CREEPY: last XMR hardfork made on October 8 2018 had involved Cryptonote v8 (cn/2) mining algorithm that has significant anti-ASIC improvements (I remember it because I did read a discussion on cn/2). Today, just 3 (THREE) months passed. How can one make a huge amount of new ASICs against cn/2 algo?! In 3 months?!
200 EXTRA UNKNOWN MH/s are too huge for even ASICs made in 3 months! We remember, ASICs are HARDWARE not software.
Right now:

309 MH/s Known hashrate, 200 Mh/s UNKNOWN, total 508 Mh/s
P.S. May it be a bug in a block candidate confirmation unit? Or generally speaking, a bug in XMR source code somewhere... may be in cn/2 algo itself?
