Leaning for density altitude

My weird observation:

Both my flight schools had relatively the same Make/Models on the line. The two field elevations are only 300ft different.

Yet at my current flight school, we hardly ever get fowled plugs from start up to run-up.
It is like pulling teeth here to get people to lean for taxi, because in there eyes it doesn't change anything.

Any ideas why our plugs don't get fowled? Is it something to do with MX?

See how much RPM rise you will get at Idle when you go kill the engine from full rich on both planes. Different MX centers each have their settings that they like to use I found out in my experiance.
