Break in oil

I use
•LubriPlate 105 assembly grease on the main, rod bearings, timing chain and other lightly loaded surfaces.
•Moroso Moly cam lube on the cam lobes and lifter surfaces, push rod and rocker arm contact points.
•10w30 motor oil, non synthetic, something inexpensive with a cheap oil filter.
•Comp Cam engine break in additive, one bottle.
•Prior to the initial engine start: I am crazy particular about part cleanliness during assembly and getting clearances and torques right.
•Immediately before the engine start: with the spark plugs removed using the starter I spin the engine for 10 to 15 seconds at a time until I see oil pressure on the mechanical oil pressure gauge. Then promptly re install the spark plugs.
•At the initial engine start: I have ignition, fuel-air setting right to get a quick engine start. I will give the intake a shot of ether to assist with a quick start.
Then run the engine at 2000 to 2500 rpm for 20 minutes. Then shut the engine down and let it cool completely and re peat the 2000 to 2500 rpm for 20 minutes followed by a complete cool down.
•Start up and drive the vehicle for 20 to 25 miles at changing low to medium to very short bursts of high engine speeds and up to medium loads.
•Drain the break in oil, replace with a quality oil of choice, a good oil filter a second bottle of Comp Cam break in additive and drive the vehicle as I intend to.
I have never had a break in issue.
A successful engine start and break in is a process, one item like high priced break in oil is not going to over come other poor practices in the engine build or initial start and run in process.
