Exactly, well written. I'll just add that there are actually two methods of sending AF list in RDS, and with method B there can be sent multiple (max. 8) AF lists with up to 12 frequencies, so it can be used by stations which needs to send more than 25 alternative frequencies on single transmitter, or to differentiate between frequencies belonging to different regions, which can broadcast different regional programs at times. This is reffered as AF REG (or Regional) on OEM or big brands units. it is actually used by several multi-regional stations here, as I've observed... But, for now, correctly working simple AF without the B method would be huge improvement ;-)
By the way, as it seems by your description in the second paragraph, that you have similar experience with AF like I do, did you notice any difference with this in the 3.6 version? Since the AF optimalisations were listed in the changelog and after updating I'm experiencing still the same glitches, I thought maybe I need to do a full reflash with factory reset for the changes to apply corretly, but maybe there are not that significant changes and we simply need to wait a bit more for the devs to come back from holidays and look into this a bit more...
