A lot of muddying here. If the original poster is who I think; my post stands. Corporate planes rarely optimize the runway performance like airlines. They just assume it’s a balanced field and take the numbers. If the BFL on a middle weight G6000 is 4,000’ and TORA is 8,000’, they take the BFL case, V1=Vr and go. There’s no need to optimize payloads vs. runway available and, with exceptions, obstacles are rarely limiting. Limiting runways are uncommon, but happen.
