So don't prolong my downshifts then? Which technique that I listed above would y'all recommend for an automatic?

When an automatic you have to toss load out the window, because it would cause a downshift. Rather, aim for higher gears and lower rpms.

-Extended acceleration with drawn out downshifts @ X-RPMs until target speed.

OR...

-Shortened acceleration with quicker downshifts @ X-RPMs until target speed.

I'm not sure what you mean by these. The idea is to not downshift at all, until you're reaching lower rpms that make this more feasible.

Example: I have accelerated from a stop up to 2,000-2,400 RPMs and held it in that RPM range using a certain throttle pressure until I get into overdrive............is this the wrong way to accelerate?

I tend to shift between 1500 and 2000 rpms, but go by feel, and don't pay much attention to the numbers.

The idea is to upshift as soon as possible, i.e. at lower rpms.

Based on not having used overdrive, I would avoid using it, unless someone else can explain that using it is efficient.

I've always used overdrive and it has provided the best return on fuel economy, the UltraGauge also supports this.

I'm sorry for the confusion. All I'd like to know is the most efficient way to accelerate for an automatic transmission to get into top gear as soon as possible at the least amount of fuel consumed.
