FWIW, I used to harvest slurry from spent primary, store it in the fridge, and pitch direct. Mostly effective, but lag times in the range of 24-36 hrs. Now I use SNS and overbuild for storage. Lag times in the range of 4-8 hrs.
I make 750ml of fresh 1.040 starter. 500ml in a 1/2G jar, 250ml in a pint jar. The 500ml gets pitched into a fresh 4G batch of beer as close to high krausen as possible (12-24hrs). The 250ml gets fermented all the way out and then stored in the fridge for next time.
