Sometimes I read car mag writeups and they talk about how cool it is to make the throttle blip while they're waiting at a light by moving the shifter around in neutral. I always wondered what they were smoking and just chalked it up to ignorant journalists talking out of their proverbial a$$e$. Well now I know differently. So here's what I don't get. Say you're in 4th gear, you move the shifter into neutral and it immediately blips. Well, how does it know your intent is to downshift to 3rd rather than upshift to 5th? This is why I say my SRM is working exactly the way I want it. I don't want it blipping until I've moved into the gate for a lower gear.
My experience with SRM is that it pre-blips and then does another final blip when you engage the gear, depending on where you are shifting. I think of the gates not only as individuals for each gear, but also based on pairs of gears with respect to the three neutral positions (between 1/2, 3/4, and 5/6).

Here:

1 3 5
|-|-|
2 4 6

If you're in 6 and go to neutral but keep the shift knob to the far right without passing into the middle neutral gate, you'll get a 5th gear blip. If you instead go from 6th to 'full' neutral between 3rd and 4th gears, you'll get a 4th gear blip as you pass from far right neutral into the middle neutral zone. If your next move is to 3rd gear, you'll get a second blip for the 3rd gear RPM. So, in my experience SRM looks not only at individual gear selection but also which neutral gate you're passing through. Passing a neutral gate gets a blip for the highest gear (2nd or 4th) that you can enter from that neutral position. To get a blip for the lower gear in that position, you have to commit to that gear (1st, 3rd, or 5th).

An attempt to answer the mystery of how SRM determines to blip or not blip from 4-3 vs 4-5. More conjecture along the three neutral zone gate theory: If you're in 4th, SRM may look for the 3rd gate to trip before blipping. So a shift from 4-5 won't blip as you never commit to 3rd. It seems SRM will blip under one of two conditions. Condition #1: a shift to a lower gear that crosses from one neutral gate to the next (neutral between 5/6 to between 3/4) which gets a blip for the highest gear of the neutral gate you are entering. Condition #2: a shift from a neutral gate INTO the lower gear of the neutral gate pair (5/6 neutral up into 5, 3/4 N up into 3, or 1/2 N up into 1).
