You can't draw that conclusion from a sample of size 4, the variance is too high. In other words: if you were lucky today, it doesn't mean you will also be lucky tomorrow.
Let me remind you that this is a PPS pool, which means predictable earnings, so it makes little sense to look at how many blocks were actually found. I would instead compare your earnings at the pool with the statistically expected rewards of solo mining.
Well as I was bored, I've done over 5 billion shares and am running at 97.17% of average, which given it has paid out 100-108% almost all the time I have been on seems about right to me.
And another random fact that pooler might find interesting, I got one of the very first titan's and was ranked #3 at the time, it's still going strong but now at #7607 :-)
yeah..I was 12 at one time...if only I'd drunk the kool-aid and not been like 99.999% of folk and NOT shifted LTC to BTC (hard not to do when majority of my mining was below
a $4.15 LTC price....ah.....the home in Belize ....poof!) I think it was 16,000 some LTC shows on LTC pool.
alas
I panic sold today, so I see LTC is rising..." your all welcome" (we also serve, who run and panic the LTC universe)
