'08 G35X auto downshifting hard on declines
It sucks when you constantly drive back and forth from the city. When I drive into boston my throttle is so laggy and unresponsive sometimes. And when I come back to suburbs the throttle is so responsive, when i don't need it to be. I guess the car is like a women, you always need time to figure them out. 
LOL..How do I reset my ECU? When I got the car I used to get 14mpg now, but since then I have matured up and get around 22mpg. 
I still have a heavy foot but I try to control it at all times.
Yea, When you leave your car in DS going downhill it will keep it in a lower gear at higher RPMS. It's pretty normal.

What the OP might be experiencing is a harder downshift than the downshift and higher rev. Over time mine has come to the point that it slams into the lower gear with a very pronounced thud. I plan on taking it in under the power train warranty.

Going from 5th straight to 3rd with a pronounced throttle blip and rev match is perhaps the most exciting thing about my commute to work every morning. This feature is to be embraced, not be bothered by. It is there to improve handling as it prevents the car from nose diving during the downshift and upsetting the car's balance, especially when entering a turn.
Also, I've noticed the car's adaptive shifting strategy is like a puppy that gets and remains excited until you bore it to the point where it loses interest.
If I drive easy for a few days when it rains for example, it shifts a lot smoother as if it learns that I prefer a smooth ride. Getting on it, however, will entice "the puppy" to behave in a more playful manner.
So could it be that after you drive the car in a "spirited fashion" and your wife gets in to drive afterwards, the car still thinks you want to "play around" and therefore holds the revs longer and overall acts as if it expects you (or her in this case) to keep driving the same way you did the last time the car was driven?
