more WUs done per day - less credit

(moderation:
New Einstein Client
cpu time: 7,474.56
claimed credit: 17.84
Old version of Einstein
cpu time: 19,028.72
claimed credit: 44.19
Basically something is wrong here - science wants me to do more WUs, but gives me less credit for doing this. I am happy to donate the price of electricity for the crunching etc, but would like to have the credits reflect this.

use common sense dude.... I'm sure you know math....

So I would have to do almost 3 times as many work units to achieve the same credit - sorry, that doesn't seem right. Maths ? Well at MY age I usually grab a calculator, and ideally get someone else to push the buttons... :)

Hrm, quick math:
19028.72 / 7474.56 = 2.545798
2.545798 * 17.84 = 45.42
So in 19028.72 seconds you will make 45.42 instead of 44.19....
Where are you making less?
You calculate by time, not by the result you crunch.

yup, interesting point you make (and thanks for pressing the buttons for this old fogey :) )
I take your point about the value of the seconds in relation to credit. I was thinking value of the WU in relation to credit.
So the time taken affects the value of the work unit - for example if I chose to slow down my cpu somehow, some form of control there, I would actually get more credit per work unit, because it would take longer to be crunched?
But surely science would prefer as many WUs done as possible in as short a time as possible (more effective crunching ?).
If I seem obtuse, bear with me - way too many grey hairs here...

Gray,
In slowing, or under-clocking, your rig, you would only get more credit until the next benchmark caught the underclock, at which time it would drop your credit/sec accordingly.
In the same vein, if I OC my rig right to the gills solely for the benchies, then scale it back to a more conservative speed for crunching, I will get slightly more credit/sec, until, (again) 5 days later (or whenever I manually run the benchies). If I do this every 5 days, I could maximize the credit return while still maintaining the maximum WU throughput, though on my rig, I already have it clocked so high (reliably) that there is only another 1-1.5% headroom anyway, ambient temperatures permitting.

I was wondering when you would appear - I assume you do sleep sometime ? (grin)
I suppose I could have done it the way you suggest, but I tend to be amazingly honest (in my not totally humble opinion), so cannot do that (even if I do enjoy micromanagement...). Thanks for the suggestion.
It just seems weird that I could go to the trouble of (for example) setting up a GUI-free, kernel-optimised, 3 gig-plus brained, seriously skinny linux box (well I can't tweak XP much more than I have - grin ), and then get some bloke come along with a 650 mHz cpu, running Nortons A/V, around 100 pieces of spyware (I have seen it happen...) and doing a WU every 24 hours and that single WU gets him the same credit as (for example), the 6 work units done by my hypothetical box. I appreciate that he has spent 24 hours getting there, and I have spent 24 hours getting my 6 WUs done, but surely 6 WUS mean more to science than one ?

I think that part of the problem here is that living in South Africa we pay exorbitant fees for internet bandwidth. At present it costs the equivalent of US$100 per month for a maximum of 3GB of data throughput. So by running the new client I have got a 300% increase in performance but with no difference in credits earned but yet the costs of transferring the workunits has tripled.
I know that credits dont actually mean anything but it is fun when competing against friends.
It would be been nice to earn the credits per w/u instead of by time.
RE: It would be been nice

Issue is the size of the WUs varies, quite a bit in this project. So a 20 minute WU is worth the same as a 2 hour WU? That would not fly.
