That is why I fill the first track with directory blocks, as I said.
If there is no space on the first track, how can a member occupy any part of it?
Or, did you not read my post?

My point is first member does not start on track boundary.
As a proof I presented some data of PDS having 1 dir block and two 
members. First member (actually the second member too) does not start at 
track boundary, because both members and directory are kept in (part of) 
first track. Ergo, there is no reason to take care how many dir blocks 
occupy exactly one member - the space between end of directory and any 
track boundary is used for members.
