Hello David.
Thanks for the responses and for the numbers below.

I have to agree that 4.10 and 4.4 specially should always be treated 
with higher importance than the waiting-list.
My initial concern was that three years were maybe too much, but looking 
at these numbers it doesn't seem to. Obviously it will always depend on 
usage rate and I agree 4.10 is expected to increase reasonably over the 
next years so when this policy is triggered we will have a chance to 
review how the replenishment will work. On the other hand I have some 
concern about a possible deadlock or freeze in the waiting list as I see 
it as a minimum fair chance for newcomers to get some space the in a 
similar way all others had in the past.

So I think your proposal based on the numbers below make sense.

Regards
Fernando Frediani
