How fast does Block Learn parameter change?

Just say I disconnect the battery to erase any fuel map block learn stuff, then reconnect and start up on LPG and drive away. Then at a constant steady speed and load on the highway I flick it over to petrol. After that, assuming it stays on the same speed/load point, how long *roughly* would it take to learn and settle on the correct AFR trim value? Seconds? Minutes? Tens of minutes?

depends on the tune, anywhere from 0.03 to 0.20 seconds to start changing rich or lean the LTFT then however many counts after that to get to the correct LTFT value.

Next question then is - what is the count rate?
