you have to maintain profiles for energy requirements at the tracks you play to effectively utilize the engen readouts. they are raw figures obtained by dividing the velocity of the various fractions by total energy (the sum of all velocities). if you find, for instance, that no horse at your track dispenses 35% of its energy early wins with less than 31% energy remaining in the final fraction and that this horse does not show this ability, the horse is a toss.

also, engen is used to establish pars that should be used in your manual adjustment of a horse's pp line. read the prefatory material in the old yellow manual to get a handle how energy, synergy, etc. creates variants to equalize lines. doc's discussions, and schmidt's, in volumes 12-20, roughly, on the use of energy par values and their creation should help.

as an observation, you seem distracted by the myriad of tools at your disposal, rather than focusing on their application. i would suggest you settle on one program and exclude the others until you've developed an understanding of the method behind the one; once that intuition has developed, it will help you with the others. i've found, you're only muddying your waters otherwise.
