The takeaway was - if you want to skip a gear, it can be done without straining the synchros but only if you go through all the intervening gears while the clutch is kept in as this 'steps down' the speed differences the sychros have to deal with. So:

clutch in
2 -> 3
3-> 4
clutch out
Exactly what I came across on forums during my s2000 days. The frs/brz trans is pretty similiar to the s2000 trans, aisin az6 iirc.
