hum, the statistics arent a php script ? so they are kept up2date, no  ?
so why more wrong tomorrow than today ?

hum that I hadn't thought of... but why not ? what would this change ?

I am considering that every applicant  waiting  at  DAM  stage  will  be
processed (accepted or rejected) one day, and you dont seems to agree...

Why ?

I sort of agree... but not considering extremes in statistics  mean  the
statistics are wrong,

I think that needing to remove extrems from stats because of the mess it
would create, means to me that perhaps the statistics would need 1  more
column ?

In the stats you include the "actually waiting applicants",  why  not  a
"the longest waiting applicant at this stage waits since ..." ?

The main usage of theses stats are the applicants themselves, which  are
looking for an idea of when they will be processed ? no ? In this  case,
they will say to themselves: "I am waiting  at  DAM  Approval  since  60
days, but the max waiting time is of 68 days, so  I  will  be  processed
really soon (great ;-)"

and, when they day will come they are waiting at this stage  since  more
than the maximal waiting time, they will be a little astonished, isnt'it

That's exactly why I didn't included people with a comment from  AM/DAM,
cause there is reasons why there are not processed, but for the others ?

I am not really saying the statistics are _wrong_, you  have  to  select
input before making them... but perhaps a lot  misleading  ?  don't  you
think so ?
