My understanding is that running lean will make the engine run hot. 
My 72 had problems with running too lean and dying a few years 
ago and the fellow I asked about it wondered why the pistons 
hadn't melted. He then answered his own question when he said "I 
guess the compression ratio just wasn't high enough to damage 
anything.

I tend to agree with you that normal operation usually gives good 
performance within a rather narrow mileage range, so operation 
outside that range is usually poor. 35 MPG seems way high, even 
for Imperial gallons.  ;-)
