The strength staff is a named actor. Graded on the gain it adds, not the athleticism it was handed.
The performance staff is the development machine, the strength and nutrition program and the biomechanics capability, read as a rate-lifter on developability. The engine isolates its residual from the talent and the frame upside it inherited: it credits the physical gain over the projected physical curve, removes the maturation that was coming regardless through the frame-typing prior, splits the credit between the staff, the player, and the org machine, and holds the portability test, because a real strength-development edge shows up in the next building and a borrowed one evaporates. Every read carries its confidence, sample-gated on players and years.
Credit the gain over the curve, not the maturation that was coming.
The performance staff is a rate-lifter on the physical traits: added strength and power, added velocity, and the durability base, credited where players gained beyond their projected physical curve under this staff. The gain is read against the frame-typing prior, so a reversible-skinny young player who was projected to add mass anyway earns the staff credit only for the gain over that expectation.
The player added 27 pounds and 2.8 mph, but his frame was projected to add 18 and 1.0 on its own, so the staff residual is 9 pounds and 1.8 mph, the gain over the curve. The engine credits the residual, not the maturation that was always coming. The gain over the projected physical curve is the credit; the maturation that was coming anyway is not.

A real edge shows up in the next building.
The staff is run through the portability test: does the physical-development gain follow the actor across organizations, or did it live in one gifted, young roster. A real performance fingerprint shows up in more than one building, and the read carries its confidence, gated on the sample of players and years.
The residual traveled from one organization to the next at plus 1.6 and plus 1.9 mph, which is what a real strength-development edge does. The confidence is held at 59% because the sample of players and years is modest, and the read says so out loud. A real performance edge shows up in the next building; a borrowed one evaporates.

A high-frame roster posts gains that were partly baked in.
The credit is split between the performance staff, the player, and the org's broader machine, and separated from the frame upside the roster brought in the door. A staff handed a wave of high-frame-upside prospects will post gains that were partly baked in, so the residual removes the baked-in maturation and reports what the staff actually added.
The staff posted a +3.4 KR gross gain, but +2.0 of it was frame maturation the prospects were going to produce anyway, so the net residual is +1.4, and the credit split gives the staff 40% with the frame and player carrying the rest. The read is honest about the talent that walked in the door. A high-frame roster posts gains that were partly baked in, and the residual reports only what the staff added.
Illustrative engine read on the real credit split and frame-upside separation (gross gain minus baked-in maturation equals net staff residual, split between staff, player, and machine). Composite staff, demonstration figures.
The performance staff is graded on the physical gain it adds over the baseline and whether that gain travels, not on the athleticism it was handed. The engine removes the maturation that was coming anyway, splits the credit between the staff, the player, and the machine, and holds the portability test, because a real strength-development edge shows up in the next building and a borrowed one evaporates. It credits the residual over the projected physical curve, states its confidence gated on the sample, and refuses to score a frame that was always going to fill out as a coaching win.
Isolate the residual. Test whether it travels.
Performance grades the strength and conditioning staff on the gain over the projected physical curve, removes the frame maturation that was coming regardless, splits the credit, and runs the portability test, with the confidence gated on the sample of players and years.
