Hi

I suspect that pulse pour may be when your pour a small amount, let it drain and then pour another small amount. Am I correct? Is it used with chemex? Google search did not yield much regarding definition.

Thanks it advance.

Jay, I believe some auto drip machines operate with pulses of spray of the grinds, but I confess not to know that term otherwise. (red faced.. LOL)
However, as a veteran Chemex user, I CAN say that one would/should never pour water into any pour-over device in that manner. Instead, it needs to be slow and steady. VERY slow. First, a small amount is poured to just cover the grind, allowing the fresh coffee to bloom at least 30 seconds. Then the rest of the pour commences, for some in circular pours starting from the middle and working in concentric circles. Others have their own techniques, but you only cease the pour for a few seconds to allow the water/slushy level to subside a wee bit, then we continue till we've reached our volume destination.

Rob

I am desperately trying to find a brew method that gets me under  4 minutes. The brewing seems much slower with decaf.

How critical is the four minute mark?  I can achieve it for smaller batches but not for 24-32 ounces.

Why 4 minutes?
My BunnSTX drip brewer does 50 oz in less than 4 minutes, but I put a 3 hole sprayer to slow it down.
20 oz in my Chemex takes 2 minutes, counting the 30 seconds for the "bloom" phase.

There is no 4 minute factor. The very well respected Technivorm takes over 5 minutes for 40oz. Who cares, if it tastes good?

Manual pour-over brew is NOT a method for anyone in a rush, IMO.
The new Brazen brewer from Behmor (which makes the 1600 coffee roaster), which basically emulates a hand pour over (by allowing programable pre-infusion) sounds like it might be a good alternative for you.
It will retail at $199, but has programmable temperature, and other features that should make it easily worth it's price.

Have you coarsened your grind? That will speed up the extraction.
If your grinder produces too many fines, you will also clog the filter; what grinder are you using? I think some have even sifted out the fines to help with this problem, but I use a compak for mine, so don't have this problem

The water will flow faster if you grind more corase. Your grinder should be fine but with a faster flow rate you might need more grounds to get the same extraction as less grounds and a slower flow.
Play with the grind and grind dose then use what tastes best to you.
