Yeah I can't tell from that that you're mining against Coinfoundry, but you are getting shares accepted. Will ping the pool operator to look into this, you might want to share your IP address as well so he checks the logs (in a PM/email of course).

what miner are you using? the config line looks a bit different than the example lines in https://coinfoundry.org/pool/rvn

can you also post a screenshot from the miner that shows it's submitting shares to coinfoundry?

did you read my comment?

It depends how long after you pull out the block is found. With the current hashrates, I think after about 6-7 days your shares will fall out of the window and you would not get anything.

What's your wallet id?

I am not the pool operator, but if you're not seeing any stats, then it's possible that you got your config wrong and didn't mine against this pool at all. The pool is automated, so if the pool daemon picks up your submitted shares, they will be reflected in the stats and in the payouts algorithm. So for some reason, you're not submitting any shares to the pool and this should be the first thing you should be asking and trying to investigate, what is wrong on your end, that you are not submitting any shares while others are.

Payouts for uncle went out. Now is the time? :)

I still think it's largely just luck. See last block.

Since the fork, I do admit my xmrig stops mining every few minutes for a while with an error saying "no active pools, stop mining".

Yes it's normal. This is how mining works. There is no guaranteed time it takes to find a block, only estimated, but in the end it's largely about luck. Sometimes you have it, sometimes you don't.
