What does that mean - 49.75?

Good afternoon everyone!
If anyone knows, explain to me what 49.75 means?

Thanks for the quick reply!

It means that your average hashrate is about 50% less than the reported one.

At the moment it is written: 196.06 MH/s - 3.04% Avg. Hashrate over 24h
Less than this: 202.11 MH/s Reported Hashrate over 24h, or this: 225.17 MH/s Reported Hashrate, or this: 243.75 MH/s Real Time Hashrate
Which one is considered to correct (taken into account)?
