From what I saw and experienced there wasn't a problem with velocity cheating because the radar speed guns were used just enough to create an effective deterent IMO. Doesn't mean that it didn't exist but that it certainly doesn't seem to be wide-spread. Any team that was suspected was definitely scrutinized.
The NXL-modified Pact timers did seem to work effectively because I roved with the operator during several games and saw them get readings that looked accurate from clear across the field and with the highly directional mic coupled with the headset to select targei they apparently can pick out individual guns with only a foot or two between them.
Apparently they haven't been put to use outside of PSP yet but that seems to be only a matter of time.
Additionally a reliable source told me that there are definite efforts being made to combine both devices into one hand-held unit.
