All that is good but the software doesn't know your climb rate, only your guess.
Most people when answering honestly will tell you they held their water too long waiting for it to get good.
Waibel used to say below 2 knots achieved climb, go dry. Above 3 fill it up..
Other variables like streeting, height band, gustiness, and shears that need to be climbed through also affect how much weight you can carry in addition to the usual climb rate and thermal diameter.
