>What is the IDEAL pct for reclamation, I use 65pct should I go lower

100%.  One would want all tape contents to expire unto themselves, and
have such a large number of tapes that the consumptive thing called
reclamations would not be necessary.  But: this is the real world, and
we need reclamation to get back needed space and consolidate data so
that restorals don't involve a ridiculous number of mounts.
The value you choose is determined by your circumstances, observing
the above factors.
