DRK network hashrate

[DrkMiner]

Hi,
I'm seeing big fluctuations in network hashrate. it was at 130.27 GH/s and now down to 86.27 GH/s.
Why such big differences?

I get the info from P2Pool status.

Big multipools switching the networks. Some multipools are as big as the whole darkcoin network.

There are so many coins out there, people really dont care about them. Multipools are just the way to get most out of your hashrate.
