The FLI value for both Ng and T4 rise exponentially close to their limits. I've made a guess as to where this starts, but it seems to work quite alright. The real thing is probably way more complex.
I haven't studied the EC-120 FLI closely, I'm more familiar with the AS-350 series. However, I don't think your interpretation is entirely correct. Read Airbus's patent covering the VEMD, the algorithm is outlined in the document. It's not magic, but it’s not rocket science either.
