What to pitch from yeast starter?

[seanppp]

I made a yeast starter with an Erlenmeyer flast on a stir plate. I put the starter in the fridge after it spun for 18 hrs. Now it has a very thick beige layer on the bottom and a kind of gradient layer above that, which looks like the yeast is trying to settle out but it's not an especially floculent yeast (001). Picture attached. My question is, when you crash a starter, do you theoretically decant the stuff at the top, pour the next layer in the fermenter, and leave the stuff at the bottom behind?

You see the .5-1 mm layer of white stuff on the bottom. That is what you want.
I typically pour off 80% of the liquid, swirl, and pitch.
