I know someone told me how much they pour per 5 seconds (or something like that) when doing pour-over, but I cannot find it now. Does anyone have a good method of doing this for Chemex?

Pour rates vary. Some like a steady linear infusion while others brew with a curve i.e. large dose after pre-infusion, then slowly and steadily "riding" the bloom. Are you using paper or Kone for your filter?

Pour rate is delivery rate.
It's adjusted to achieve the desired overall contact time.
Some people do a pulse pour. Some do a constant pour (see G. Howell's video) in a couple of stages. If you're Starbuck's, you dump all the water into the pourover in about 15 seconds.
A great starting point is to do a bloom pour, start the timer, and attempt to achieve about 3:30 to 4:00 total delivery time. The last bit of the percolation will be fine - the temp of the brew water is dropping, so you won't suck the bitter life out of the last bit of grounds. If it tastes overextracted, then increase the grind size, or keep it the same and terminate the delivery 20% earlier and just dump the rest of the brew water into the cup (in essence, do a "bypass" brew). Lots of options.

So I think, then, I just need to pour slower. I had consistently been getting 3:20 - 3:30 for 320-350ml through 21/22g of coffee in our Chemex. It seems I have sped things up. Ha.

What makes you slow in coffee pouring is the carafe spout. Be sure in buying a coffee maker; try to examine well the spout. The wider spout design makes it easier for you to safely pour a cup of coffee.
