OMG! Recently supernova testnet pool had a massive 6 500 Mh/s!

I'm starting to thing that this numbers are kind of random. Or how/why else there could be in the TESTNET 10x power of all other equihash coins combined?
don't panic, testnet is good:
Network Difficulty 9064914
Network Hashrate 1.75 MSol/s
Blockchain Height 5430
Node Connections 40
