(Assuming this is about zita-ajbridge)
No, zita-j2a and a2j measures the relative timing of Jack and Alsa periods
when starting up. With the -S option (no resampling, assuming word clock
sync), this is a single observation and there may be some remaining error.
With resampling (no -S) the added latency will converge to a defined value,
with only some jitter around this remaining.

Indeed no, the anti-aliasing filter is part of the resampling process.
