In my my aircraft the numbers run about 250 feet for every 10 degrees above ISA/200 feet for every 10 below Autobrakes 2 on a dry runway. Why Boeing doesn't just say 25 or 20 feet per degree I don't know. EDI is sea level so if it is 25c add 250 for temperature adjustment. If the airport elevation is 2000 feet MSL and it is 30c you would add 475. 30- ((15-(2x2)) X 25.
