Solo mining with 250MH, wasting my time?

Thought I'd give solo mining a crack cause I'm generally lucky in life. Have noticed plenty of blocks found and payouts with luck from 6%-170% with hashrates ranging from 100MH to 90GH. (Plenty blocks found by people with less than 50% luck and hashrates lower than mine)

Only been at it 2 days and my luck is up to 10%, has anyone had any actual experience solo mining with small hashrates?

How long did it take to get a block? I know it's luck based and not something you can really predict but would like to hear from people who have done it to see how their luck was.

Worked out if I can get a block within 26 days I'll have made the right decision, more than that and I'd have been better in a pool

Only 2 days in but nervous already :/
