That is called an arithmetic progression (from my school days)

does not resemble a geometric progression.
Lets have a LOGICAL numbering system. How about
Centos 6.6-1503 ........
derived from {major}{sub}{yymm}.
But what happens when 2 or more revisions occur within the same month ?
Will we have Centos 7.1504 and 7.1504a and 7.1504c or will someone
decide to use 7.1505 (= May 2015) whilst still in April ?
Clarity is important in all things 'computer'.

Maths was my favourite school subject too.
