The reason for this is that during T/O the cooling airflow is low and the engines are not designed to run at above 75% power without a full (over rich) rich setting. I do my engine runup after the oil temp is up at no more than 1,800 RPM checking for mag drop, oil pressure and smoothness. I check the engine instruments again during the takeoff roll just after full power is applied. I do the prop cycle check at about 1500 rpm.
