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.

The SRM does nothing at all while you are waiting at a light. The SRM can only set the engine speed based on gear ratio, if vehicle speed or transmission speed is too low then SRM is disabled. e.g. If you are crawling along in 1st at 5 mph and then try to stick it in 6th SRM isn't going to try and match RPM's to 200 rpm and stall your car.
If you are in 4th gear and shift to neutral the rpm's won't blip any higher, they will hold at the 4th gear rpm until you either select 3rd or move to another neutral position lining up under a different gear pair. Likewise if you are in 6th and move to the neutral position above 6th it will hold the current rpm until you move the shifter to the neutral position above 4th, at which time it will blip to match 4th gear, and blip higher still if you move to 3rd gear.
With all of these movements if you leave the shifter position still for about 1500-2000ms with the clutch in then the rpm's will drop to idle (or whatever your right foot is otherwise commanding).
