Because it's a known quantity, if your setting the engine up with EGT, det counter and or CHT you don't want anything else that could influence what your looking for. Plus it's a constant oil ratio what ever jet size you use, you'd have to change a jet and the oil ratio to give you the same ratio you had before. Which seems hard work in my eyes lol.
I have nothing against pre-mix thats all I use to be honest, but IMO for a stock to slightly modified keep it simple.
