Covered....as I mentioned a couple days ago....my 42/day will start later today once current LLTF completed

Thanks! To you, and everyone who answered the "surge" request, and/or gave permission for a LLTF to DCTF change for LGPU72D.

Based on what is queued we're looking good for staying ahead of the Cat 4 DC'ers (mostly AKA "the churners"), but probably next week I'll update the assignment code such that LLTF LGPU72D requests may occasionally assign some DCTF work.

This will probably not be needed to be used (unless a new MP is found, and we get a new surge of Newbies like last time). Also, please know that this will only be used to stay ahead of the LL'ing Cat 4 wave front. Or, in other words, only working from 71 bits to 72 at the DCTF'ing wave back.

I've just switched over to DCTF, and I was assigned this exponent from GPU72 (along with some other similar ones):

78986359 DC TF 71 74

As far as I can tell that exponent has never had an LL done, and it is much too high to be the current wavefront for double checks, so I am a bit confused. What am I missing?

I would also like to see that option.

A little confused....

If I understand correctly the "LL'ing Cat 4 Wave Front" is about 72.6M
Isn't the "DCTF'ing wave back" about 58M?

I am currently taking the lowest DCTF to 72 Bits. About 40.8M.
Is this not what you were needing for the DC Churners?

This doesn't make sense for DCTF'ing.

Code:
| Chris Smith     | 2015-06-02 18:57:52 | DF(9) -- N:    1 G:  150 P: 75 L:         0 H: 100000000 -- n:  100 p: 74 l:  66000000 h:  80000000 -- A: 4

I misspoke. s/stay ahead of the LL'ing Cat 4 wave front/stay ahead of the DC[LL]'ing Cat 4 wave front/ should be more correct.

If that was me, I'd assume if I selected "Let GPU72 decide" and "75" that it would interpret it as "Give me something to do, whatever is most useful right now, and I'm willing to TF as high as 275 if that's required".

Fsck me...

Thanks, you've pointed out a bug. LGPU72D for DCTF hasn't had an audit recently. Sorry about that.

I'm doing the best I can with the time allowed.

Ah okay. MISFIT greys out that option so I just assumed it wasn't important for LGPU72 decide.
