One thing they forgot to mention is that when the VVDS shrinks it
doesn't release the space that it formally used on the volume.
I think its a start but depending on use the 10,10 trk allocation is
just plain shortsighted on some volumes. IOW know your data.

the size of the VVDS depend on mix of VSAM and non-VSAM datasets and
possibly even the type of VSAM datasets on the volume?
There is a formula to calculate the size of a VVDS base on the
number of KSDS, ESDS/RRDS, LINEAR, and NONVSAM datasets.
