are you trying to imply that with a steady network HR the reduced variance of pooled mining will yield you more BTC than solo mining?
Oh god this is ridiculous. If you solo mine you may get "lucky", and get a better payout. You might also be unlucky and get a
worse payout. Unless you have TH/s the amount you earn will be dominated by your luck, not your hashrate.
Your "Personal experience" is irrelevant. It could change at any moment.
there is no such thing as "luck" when mining. it is all statistically based.
