I just watched the video - good job, and I like the t-shirts!
I took a short flight yesterday*.
I propped up my iPhone and video'd my post-flight burping:

Two observations:
1) I don't feel the oil level change with temp is that large. Engines are routinely checked at operating temp, and I've never noticed a difference between hot and cold.
2) Can of worms here, but I don't think having oil in the tank prior to engine start is necessarily an advantage. Dry sump engines have routinely been started without oil in the tank for a long, long time with no apparent ill effect. It will take a certain number of turns to get oil into the tank and to build oil pressure, and there's no advantage to doing it slowly - bare metal scraping over bare metal is bad whether done fast or slow. Best thing is to get oil pressure and temps up as soon as possible, which is best done by just starting the engine.
I believe both Continental and Lycoming have moved away from recommending their engines be "pulled through", even when cold starting.
But like I said, a can of worms and whatever works for you!
*over Lake Blue Ridge to watch the moonrise. Can barely make out the moon in the second two photos, but in real life it was gorgeous!
