Good rule, Flyn.
A bit like you, I've always operated on the premise that I could probably wring about 250 kms (155 miles) out of a tank, and I've tended to want to fill up around 230 kms. The beauty of Noroomtomove's First Law of Motion and Fuel Consumption is that I'm now pretty comfortable that touring I can get a more than that without becoming too anxious.
On a recent trip my reserve light has usually started flashing at around 210 kms (130 miles). Applying NRTM's Law tells me I have another 84 kms (52 miles) up my sleeve which is an extra 44 kms (27 miles) over my normal expectation—294 kms total rather than 250 kms. However, if the thing starts flashing at 165 kms (102 miles), I've got only 66 kms (41 miles) and I need to be much more concerned about filling up. Plenty of city riding dramatically reduces my fuel economy.
