i really don't get why it would have worse or better sync depending on 
jackd latency settings. please forgive me, but i don't see it directly 
related to the case of audio vs. midi sync...

though, in the special case that comes to mind, iif the alsa-midi timer 
is slaved to a pcm sound-device, as against to the system or hires timer 
for instance, you probably will get it different whether running on 
disparate buffer-sizes, periods and/or sample-rates, that's for 
granted--well, if you change the sample-rate across sessions you will 
get prompted to convert into a brand new and different session anyhow ;)
