Repacking without '--force' (for gc) or '--no-reuse-delta' (low level)
would always reuse this tight packing. Only with '--force' you would
waste CPU trying to find better deltaification[*1*].

So what you are doing is passing the work, unnecessary work I'd say,
to some poor server. Not nice.


[*1*] I hope that '--no-reuse-delta' means _try_ to find better delta,
but use current one as possible delta, not stupid forget about current
deltaification at all...
