<<
if you construct a system on time bars, then having an identical tick
database is not as critical if you have constructed that same system
on tick bars.
my research has shown that a difference of even one tick between
databases on different computers can cause large variations in tick
bar system (or indicator) sensitivities, especially momentum
(velocity) and particularly accelerated momentum (acceleration).

This is not abnormal.
The conditons should match in any comparison case .

in addition, maxbarsback should be set on manual rather than auto
detect to maintain system compatibilities on different computers.

Yes, but this is true only for indicators.
The Autodetect feature is (fortunately) UNAVAILABLE to trading systems.
Sincerely,
