Are there any news/progress with roll-n-time support for cgminer?
Will this feature be available soon?
Should be done today I hope, but needs some testing too.
I hope it will be up and running sometime this weekend. We'll find out soon.

Ready 2 test!

Whenever it is implemented, you will see it in 2 places:
1) The E: on the top will go up - with a MiniRig you should get a VERY high number.
I get 1170% with a single BFL single - i.e. I generate on average 11.7 shares per getwork (i.e. 10.7 extra)
2) Also, if you look at the API "stats" command it will specifically tell you the pool's roll-n-time settings for the last getwork.
There are 4 fields:
Work Had Roll Time: If the last getwork actually had a "X-Roll-Ntime" header
Work Can Roll: if the header said it can roll (the header can also say it can't roll)
Work Had Expire: if the header correctly included an expire
Work Roll Time: the expire value (seconds)
Of course make sure you are using the latest cgminer to see all that.
(API stats pool roll info was added in 2.7.4)
