Sorry for taking so long. By "baseline" I mean common rated thrust, in this instance Maximum Continuous Thrust for the 900. Upgrades are for thrust that is available short term? So here, at burst, the 972 was not performing any different than a 900 would be. Maximum continuous thrust in the climb, or some lesser value?? What is different? The DEP makes available for short periods augmented thrust from the same core. The restriction on this excess thrust is the crux of the discussion, imo. Either it is a proven design, or it is not, and if not, it has no place bolted to a wing, only to a stand. So my question is as before? Where does this rather substantial thrust come from? The same Core? At the same RPMs?? This implies a merely "derated" 900, and an "augmented" 972?? There is to me a discrepancy.
