Always the same.  I had shares, what gives?

Nonsense.  A pointless, stupid response.

[kiwiasian]

Lol?

Nonsense--your question is pointless and stupid.

You may think that child, then leave it alone.

Maybe someone of a helpful disposition who actually knows something will be kind enough to respond.

It's normal, very short rounds (10 seconds - 2 minutes) are pure luck. If you are among the first to get shares you get paid a lot.
If you are among the last you get no reward.

I've had even 3 minute rounds where I recieved "none" (6.5ghash on slush total). The longer a round lasts the more chances you have to get paid.

In over 99% of cases you get paid for every round. Even at very high hashrate, the chance to find a block within a few seconds is far under 1%.
Those rounds are statistically abnormal, but by no means impossible (pure variance), just as a royal flush in a game of poker.

Absolutely incorrect.

Besides of that - it would be helpful when the statistic site displays the number of shares, that my worker produced, as well and not just the total number and my reward.
That way everybody is able to see if any shares were coming in..

If it says none, then you really had 0 shares that round. If you recieved even a small payment then you had at least 1 share.

It's very common if the round lasts only some seconds, no matter how much hashing power you have. It's a luck of the draw.

AFAIK Slush does not support LP.  You also have a ridiculously low hash rate judging by your other rewards.  Here's probably what happened.  You got sent some work units to solve towards the end of the previous round.  Your computer finished those and submitted after that round was over, therefore they were stale.  You received new work and didn't finish it within the 35 second round.

So yes, you did have shares, but they didn't count because they were stale by the time you sent them back.  Even at 2GH/s I sometimes get extremely unlucky and have rounds with only a couple of shares and a very low payout.  There are other times that I get extremely lucky and end up with twice my expected payout on very short rounds.

That's my best edumacated guess.

I haven't used slush's pool in quite some time, so I don't know if anything changed or not.

In short rounds, not everyone has a chance to submit shares. The higher your hash rate, the better chance you have of getting a few shares in a short round. If you do submit a decent amount of shares, you will get a decent pay out.

OP, I would assume that you submitted 0 shares for that 35 second round. Are you 100% certain you submitted shares for that round? From your very small payouts on the other rounds, I have to assume you hash rate is quite small and that you simply did not submit any shares for the short round, and therefor received no payout.

As the previous poster mentioned, perhaps any shares you did submit were stale.

Simple answer: You must submit shares to receive a reward.

I remember the 3 second round on slush's pool that has 8 shares submitted. Lucky I managed to submit one of those 8 shares. That was a 6 coin payout per share!

On second thought, I'm sorry I gave you any answer at all.  This kind of attitude is ridiculous.

Ah, thanks for the responses. I misunderstood the shares column, it is total shares and I must have not managed to submit any in the time because of my low hash rate, or else had submitted stale ones because there is no long polling on Slush's pool to eliminate those.  Makes sense now.  Partly luck of the draw, partly that my poor nvidia little GPU can't keep pace with the big mining rigs.

@tito Yes it is ridiculous to respond to blatant trolling but I am only human.

I think it's a proper response to blatant misinformation. People who don't know what they are talking about shouldn't be providing others with answers.
