Why does the hashrate of the Qubic mining pool in Monero fluctuate so much?

The hashrate fluctuates because miners join and leave the pool as they see fit: they change servers in search of better pay, turn rigs on and off, or run tests.

In small pools, when a big miner leaves, power drops and sharp swings appear.
