No; the calculation works with "all" values. It's whether or not the values are correct for the application, and that will determine how spreads are detected and what happens when they are detected.
And, all Control Constants are not always the same for every Frame size GE-design heavy duty gas turbine. Many are, but sometimes Constants for functions like these are not the same. And, since GE Belfort was likely involved at some point with this unit (a 6FA) we can presume there are differences--some subtle, and some not so subtle.
I agree--the values of Control Constants should be confirmed with the packager if there is any question. But, we don't know a LOT about this situation. Has the unit previously run on gas fuel? Is this the first time the unit has run on gas fuel? Were there spread issues before this outage which are causing concern? Is this a new unit--or a unit being retrofitted to run natural gas, or some new gas with possibly different heating content?
Patience, sir. Patience is a virtue. And, Control.com is a good place to learn patience. It can also be frustrating if you don't have any. We will hear back if and when the poster decides it's beneficial to post feedback. Some recognize the benefit of posting feedback to others; most will only post feedback if they deem it's somehow beneficial to them personally to do so. All we can hope is that we encourage more of the latter to post feedback like the former--because that is the benefit to these World Wide Web forums.
BUT, we also have to realize--we are not always going to get feedback. Control.com is pretty unique in that, in my experience, more posters supply feedback than on a lot of other similar forums (fora, as some would have us refer to them!). But those that do provide feedback make this a really good site.
