Please be patient and try to read all of this attentively...
I would very much appreciate your reactions.

In my view the credit system as it is (1 delivered WU compared with x others - before validation and receipt of credits), will react pretty much the same as a nuclear reactor or an atomic bomb.

It is possible having the figures of the database to predict whether or not depending on the amount of users who turn in valuable WU's if the system as a whole has the following conduct :
1. Supercritically = tremendously increasing in time
2. Critically = sustained (controlled) process
3. Subcritically = process comes eventually to a dead stop

Let us go back to the analogy :

U235 for example undergoes spontaneous fission with emission of 2 neutrons (call this your x WU's), each of which may induce another U235 nucleus to fission.
If this process continues an increasing chain reaction (of production of WU's)occurs.
However some neutrons are leaving the material before colliding with another nucleus and these will be wasted (approximately the same thing will happen with some WU's - for all kinds of reasons...).
Therefore the fractional change in the number of nuclei undergoing fission (read WU's undergoing acceptance) is reduced from 2 for U235 (read this x WU's) for U235 to F = N'/N.
N = number of nuclei which underwent spontaneous fission
N' = number that were induced to fission by the original N

Translate all this to WU's - 1 WU granted for credit by x other in the same pool, so you must have pretty much the same situation as in a "CONTROLLED NUCLEAR REACTOR".

I don't think this should give very much difficulty to figure this out once the boundaries are set up and could give "SOME VERY VALUABLE INFORMATION CONCERNING THE EVOLUTION OF THE CREDIT SYSTEM AS A WHOLE".

I'm hoping to get some serious reaction toward this thinking pattern,

Note this are only some preliminary thoughts. Within a few days I'll present something more arithmetically coherent...

Addendum :

Of course it would be of much help if the streams in and out of the WU pool at least could be given an initial estimate to establish an order of magnitude.
Other important factors are the amount of wasted WU's and how many times an average WU has to be resend before "success".
In this way the above described raw model could be more refined to give more accurate prognoses.
