Hello there, how would the developers assess the validity of reduced T/o thrust flex temperatures suggested by Simbrief, in particular those provided with their airframe preset for the RJ100 variant? The v speed values are always close to the booklet in the cockpit, but whenever I have rather heavy departures, the given values lead to very poor takeoff and climb performance, in extreme case the resulting N1 settings amount to a lower thrust rating than reduced climb thrust. I wouldn't say it is outright wrong, for example the long runways of Athens allow for a 50 second takeoff run and RTO one knot before V2, yet not nearly with the margins presented by simbrief. Also the climb was easily within said departure's minimum climb gradient, but I can't imagine it is meant to be flown in such shallow climbs. So what could be a better source? Thanks.
