The simulation shows that even wear is achieved among available equipment.
When it becomes unavailable, equipment #1 is sent to last position
(sorRunTim.yIdx[3]=1
),
and automatically moves up in the staging order only if another
equipment (#3) becomes unavailable
(sorRunTim.yIdx[3]=3
and sorRunTim.yIdx[2]=1
).
We can verify that no equipment gets "hot swapped".
