Why in the world would you want to retard timing when you’re tipping in on the throttle???
Not exactly true.

Whenever you take your foot off the throttle while cruising at 5k or any rpm, as in shifting gears, it pulls the timing back 10 degrees (good for emissions and you'll never notice it) but as soon as you touch the go pedal you get an instant 10 degree kick and throttle response to boot.

Again, them engineers were dang smart!
