A--P,
no need for confusion, as far as you need to know when you are pushing the TL with your 'sweaty hand', as Jonathon puts it. You only need to know that the 2 donks will be producing the same thrust, at the correct rating for the a/c type. The a/c does know if you have put the wrong thrust rating plug onto one engine and won't let you start the engine.
For the 524H vs 524HT comment on Temperature, assuming we are talking EGT. The probes are in exactly the same place on both types. The core is 80% Trent 700 technology. And it does genuinely run at least 35degC lower than the pre-T version.
As mentioned above, no need for such detailed knowledge of thrust rating and 'capability'. Unless that is of course you are interviewing for my job
