LEO Mining Tokens Beneficial?

I'm not sure how to tell whether I'm earning anything from my LEO Mining tokens.

I hold a very small amount of staked LEOM (about 10). While I don't expect this to make me a fortune, it would be good to know whether that value is better used elsewhere.

Occasionally, I receive a small amount of LEO from @contract_tokens. Is that the result of the miner? If so, I think it's a great investment and may even stake some more LEOM.

If anyone has some more information or some feedback for me, that would be much appreciated!
