[QUOTE=davieddy;337166]2300 LLs completed.
2300 TFed to 73+, [B]of which ~1000 were taken to 73 bits exactly. [/B]

A good week's work all round, and as I have been saying all week:
[B]IF IT AIN'T BROKE, DON'T FIX IT.[/B][/QUOTE]
How many of those that were taken to 73 were done so outside of GPUto72?
Remember that Chris in his day job manages networks, etc. Watching for trends is part of what he does.

If 1000 were taken to 73, what about the other 1300, were they taken to 74?
If so, that would be ~31 LL tests saved, beyond those saved upto 73.
Taking them to 73 saved ~32 LL's, beyond those saved taking to 72.
Taking them to 72 saved ~33 LL's, beyond those saved taking to 71.
Taking them to 71 saved ~33 LL's, beyond those saved taking to 70 (the default PrimeNet level.)
This represent a speed up of the LL testing of ~5% (extra tests not needing being done). This also benefits the DC's that will happen in that range. This also frees up the P-1'ers do look for factors even higher (if I understand P-1 correctly, the 'floor' can get pushed up by selecting the right B1 value.)

Seems like GPUto 72 is a great thing. Chris is keeping it tuned for maximum effect, based upon available power.

Enough of this innuendo already.
Stop giving me a hard time.

[B]NEWSFLASH[/B]: The world (nor this forum) does not revolve around you.
Be happy, you've received a thread that revolves around you.:smile:[/QUOTE]
This reminds me of Mach's Principle.

I'm sure Chris' motive was to encourage me to become more involved in the forum, and invite a lot of complimentary posts to crawl out of the woodwork.

DAVIDDY any interest in getting a new computer with Gpu? If u have a Paypal account I'll kick-in the first donation. I'm sure others will step up.

A few weeks ago I started a thread entitled "GIMPS demographics".
I suggested that the world hardware ownership made it slightly surprising that turning in 700 GHzdays/year got me into the top 1500 LL producers.

Plenty of scope for a discussion, and the theme would be narrowed down by the first responder.
That was Chalsall:
"How much money have you got? My GPU does 200 GHzdays per day.
[B]ARE YOU SLOW OR STUPID?"[/B]

Having been involved in all aspects of IT for half my life (=32 years) I considered this a somewhat less than constructive reply. Others described it as uncalled for and out of order.

By 1966/7 I had discovered better things to suck on than dummies.

I'm not sure what you were trying to say, but it sounds disgusting.

Consider this a bit like a modern version of street theatre....
