Manicured garden, I am assuming that the 737 is the only jet you have flown, because min clean speed is different for each machine, not the least because not all aeroplanes have a flap 40 to add whatever speed to!
The airbii and embraer jets have flap 1,2,3 etc, the 146/RJ has 18/24/36 from memory - not that it got over 25000 much!
so yes the aeroplane type matters
