No matter what you do to the map, AF or ignition, you can still have detonation (ping). I've had my '11 1200GS for right on a year. I run mid-grade 89 ron/mon divided by two because that's what my owners manual says to use. I don't recall a single case of ping. I'm just getting to the point I can feel what gear I'm in in slow turns, but do occasionally get into a lugging situation, a situation I hate and one where detonation usually occurs. Where I'm heading with all of this is the way you operate the throttle, the gear that you are in AND staying away from cheap ass low octane have IMO way more to do with ping than maps.
I believe your 1200 has a knock sensor, so if you do get pinging, the ECU will immediately pull timing. That won't help with lugging but at least the problem isn't compounded. Most modern cars have knock sensors, so hearing pinging is getting more and more rare.

In my turbo- and blower- equipped cars, pinging is VERY BAD. I once read that one ping under boost can destroy the apex seals in a Mazda RX-7 turbo.

A friend of mine swears that his '08 1200 will lose power after one tank of regular and it won't come back unless he resets the ECU, which suggests that the 1200 ECU immediately writes spark retard to the tables. He is a pretty knowledgeable guy (aka OCD Engineer, like me), so I have to believe him. It's ironic (and not in a Alanis Morrisette way) - he has a knock sensor, yet he is way more militant about Octane levels than I am because I just have to take it easy for one tank, he has to reset the ECU!

However, I agree with your comments, generally. When I got the pings on my bike, I just ran it at higher RPM in a lower gear until I used up that tank of gas. It only happened when I rolled on the throttle in 6th at low rpm to pass someone. I do have a bad habit of wacking open the throttle at low revs because the PCIII allows me to do so with no lugging (or pinging).
