P&G question!!!

Hey guys, excuse me for my noobness. But to be honest I got a question about P&G on an automatic transmission car. While getting an awesome kick out of it, like most of you do..I noticed whenever I throw it back in drive, it slows down. I know this because it's in gear and obviously drops my speed. But I noticed if I rev match it to the speed and the gear I assume I'm going into it doesn't "jerk" into gear. It keeps the speed.

But the main question is, what hurts my fuel economy more? Letting the car slow down, or bringing the engine about <1,000 RPMs up so I can keep the speed and continue on my way?

Should I even be P&G on an auto? I do know how to rev match correctly (previous fun and very not so efficient GTI's I'vd had on the past)


BTW, this site is freaking awesome. I've been driving more "eco-like" and so far I got 1/4 tank left to go when I would be empty by now.
