Yes, it learns. Thats why I reset mine. It learns my leisurely accleration (grandma style 5 days out of 2) more often than not, over the two weeks, and the punch kind of smooths out.
I'm not sure of the duration, or steepness of the learning curve, once a hard driver starts driving after a granda driver, so I just reset it.
Try it once, and you should be impressed.

Tried it this morning on a stock 2000 GS 400. I employed the "pull the fuse" method. Left it out approximately 30 minutes. Noticed very little to nothing at all. But maybe that is because I normally drive aggressively and I wasn't teaching the ECU anything new. Maybe the nerve endings in my a$$ (seat of the pants o'meter) are not quite as perceptive as the rest of the groups' OR maybe I am not fooled by what "should" work but didn't/doesn't.

^ if you normally drive aggresively, when why would there be any difference just by resetting the computer? The difference is felt by those who drive kinda leisurely for the majority of the time, then after a reset and some agressive driving, is where you'll feel the difference.

Do we know now if that is a full reset, partial reset or none at all?
Response feels better because of the filter I know, but I didn't notice a substantial improvement in performance.

I disconected the positive pattery terminal for about 15 to 20 miniutes. I was having a very slight slip of the tranny from 2 to third. Once I reset the ecu, it stop. From now on I will do it more often.

Wow, I didn't know this was an issue for non FI cars. I HAVE to re-set my ECU often since going FI because the factory ECU, as you all know, is a learning ECU and wants to override my MAP ECU. I have to reset mine once a week. I didn't realize some of you reset yours DAILY? Anyway, the shop that did my turbo kit is working on a switch that would reset the ECU and still save all the settings. You wouldn't have to pull out the fuse or disconnect the battery. I'll keep yall updated to their progress. Hopefully, this will help.
Just to throw fuel on the fire here....... 
I have had my car down the dragstrip quite a few times now. On my last trip, I made my first run, and it was a good one, pretty normal in ET, Speed and launch. Then I remembered the ECU. I popped the hood and pulled the fuse for a good 30 as some other yahoo oiled down the track and they had to clean it up.
On my next several trips down the dragstrip, with the engine at the same normal temperature, I went SLOWER!! MPH was down as well. I was pissed, it was like I just wasted my trip to the track!

Well of course you wouldn't want to reset the ECU when you're at the track...the car won't have anytime to elarn your driving style.....DUH!!
Whenever I reset mine it drives really slow and is slow to respond until it gets a better sense of what I want it to do. But that's a given we all already know.
