All of this in spades. Considering that my beautiful wife bought me a Maelstrom for my birthday I wouldn't change a thing about my starter process. In addition, I make huge amounts of yeast now and my batches also launch in less time that before.
Of course, you'll never know for sure until you try it. I completely understand that "if it ain't broke, don't fix it" thinking. But my desire to know overrides that often.
So, If I have this right this is the process.
For 5g of ale
Make a 1l starter about 1.035 using a vessel that is about 4l
After cooled add yeast
Cap vessel and shake vigorously for about 1 minute to turn volume into foam
Wait till at high krausen and pitch
Did I miss anything?
Technically, you want to shake, then add your yeast. But I did it your way and had no problems.
