Accelerating harder and short-shift to keep load up to 75-80% and achieve cruising speed in as short a time as possible is preferable to *****-footing up to speed. Accelerating yields poor economy; minimize the time spent in this mode. Accelerating at WOT in open-loop enrichment yields horrendous economy so stop short of this limit (usually 85% load in most EFI programs). Short-shifting helps keep load up and prevents high piston speeds that increase internal frictional losses in the engine. Usually 2000 rpm is good unless your engine has a very short (less than 3.25 inches or so) stroke, at which point going up in RPM is ok.
