2ms should be 200ms I guess:
First, 0.2 seconds is just the default – and much too high for modern systems! Note that this is not automatically applied to all outgoing OSC bundles. It is just a variable that is used by certain subsystems, such as Pbind/EventStreamPlayer and Server.bind.
The reason why it does not make sense to forward incoming MIDI/network messages to the Server as bundles is that it would only help to preserve the exact jitter as on the Client, which is rather pointless.
Note that for live input you also want to reduce the hardware buffer size as much as possible. See also the last few posts in this recent thread: Server clock vs. Language clock - #41 by Spacechild1. For sequencing, the hardware buffer size does not matter, so you can set it to a higher value to play it safe. It’s a bit like recording vs. mixing in a DAW.
