I also measure split to give myself a very very general idea of the efficecny. I have not been puting this info in my reports.
Where do you take readings? As close to bottom of plemum as possible, middle, or top?
What equipment (thermometer) do you use? Probe, Magnetic, non-contact infared? If you use a non-contact infared on galvanized sheetmetal, do you apply making tape, magentic sheet or something else to prevent emissivity problems?
What is the min split you find acceptable? For what weather condtions? For what type of furnace, etc.
