Guys, I love the concept of the pool and the ability to easily cash out into BTC but I'm bailing out until you sort out the problem with stales. I've been mining for about 4 months now so I've got everything pretty finely tuned. I've never had a stale problem with any other pool but this pool consistently shows my stales at about twice the pool average. Maybe your stale reporting algorithm is flawed or your pool doesn't like my mining rig (If so, you guys are the only ones)..
To give you an example, I watched round 754, a CGB round, like a hawk. Your stats consistently showed my miners running at 9 to 10% stales. I've just spent the last hour mining CGB on another pool and my stale rate is below 2%. And don't get me started about shit coins!

30-40% stales on your pool.
FYI, I'm using the latest version of guiminer scrypt and I've tried various flags and intensity adjustments but it hasn't made any difference.
Try using cgminer with these settings in your config/batch file:
--expiry 5 --queue 0 --scan-time 5
I'm testing various different settings on my rigs and the above with an intensity of 18 produces the best results for multi coin pools, for myself setting a higher intensity than 18 gives a higher amount of rejects. A few people have mentioned that modifying such settings on stratum servers has no effect, but I really do find that there is a difference and I get a much lower reject rate. Also if my miner detects a stale share and submits it, 90% of the time it is accepted:
[2013-09-19 10:35:21] Pool 0 stale share detected, submitting as user requested

I'm also using a slightly older version of cgminer (2.11.4) as I found using some of the more up to date version my cards were running hotter, may just be myself or setup but for the past 3-4 months and plenty of playing around, this has been performing best. If I mine LTC only with none of the above settings I get 1-2% rejected so I really think that the various different pools and coins take a bit of tweaking. What might be good on one is not necessarily on another.
