I never said i had no way to tell, I said I don't care, there is a difference.

When I mine solo I set awesomeminer to send me 2 different emails when a block is found but I don't do that when I mine to a pool (mostly fpps/pps+) I don't bother, most people don't I suppose, and that was my concern when NotFuzzyWarm said that pool never lost a block, anyway the answer is now clear, as for pps pools, I am pretty sure they operate on the right server and with the proper code, highly unlikely that nowadays pps pools lose a block for any reason but "bad luck", despite the fees running a pool on fpps has a lot of risks, losing blocks is something they would never want happen.

Also, one thing to keep in mind that losing a block due to bad luck and not technical deficiencies has to do how many blocks a pool is subject to find in the first place, Kano pool hardly finds any blocks on the grand scheme of things, I even saw him brag about not mining an empty block in my empty blocks analysis topic , I didn't want to comment on his topic on that section to not trigger him there and make members of that section suffer reading his disrespectful replies, it's enough that members of mining board are suffering. 

what Kano seems to don't know or ignore is that the probability of him hitting an orphan/empty block is directly related to his chances of hitting a block in the first place, given the tiny hashrate he has compared to the large pools it makes sense why he is unlikely to hit an empty or orphan block, of course, with all technical aspects like having the right code, server, and connection being equal.

Think about it this way, what is the probability of a coin landing on its side when you toss it 1 time vs 1000 time?, Kano said the time to verify and construct a block is less than 2 seconds, so applying "cumulative distribution function aka CDF of the exponential distribution" on his numbers we get:

exp(−1/60)−exp(−2/60) = 0.016 or 1.6%, all miners combined are expected to hit a block between 1 and 2 seconds at a probability of 1.6%, what is Kano's hashrate % compared to the whole network?

90,000,000TH vs 10,241THs ? 0.011%, the chances of collision with another pool and hitting an empty block are close to 0, so not finding orphan or empty blocks is fairly based on his tiny little share of the total network hashrate.

To be fair, of course, this doesn't negate that fact his pool's infrastructure is good enough to maintain his tiny 0.011% chances at 100% whereby he doesn't lose the blocks he hardly finds, so that's good overall, but it doesn't make his pool better than those pools that lose blocks due to "bad luck", and regardless of anything I highly doubt he runs a better code or owns a better server than those multi-billion $ pools, but it's good to have a few small pools around, in fact, if he wasn't such a jerk - I would point at least 2-3ph to his pool, but with his attitude, not a chance in hell.
