My gripe is that there is NO REASON for a vendor to be stingy with

THANK YOU!!!!!!!! I took so much crap for this one. Guess you and I are
the only ones that think running out of directory blocks during maintenance
because the initial install specified 10 is stupid.
I agree completely with this. I did question the multiple of 45, but PDS
directories should be allocated with plenty of space. For a very small directory
(maybe under 20 blocks) I like to see at least double what is used. For a large
directory (maybe 500 blocks) I like to see at least 20% free. Maybe a little
less if it is a load library and no growth is expected.
I think everyone agrees that directory should have safe margin for
updates. However the discussion was about magic numbers like 44,45, or
46. Spare directory blocks are obvious, any of the numbers above not.
Despite of discussion noone explained why these numbers (or at least any
of them) are so magic. Hint: "fit in the track" is absolutely not
reasonable.
