10-15 minutes slow depending on how I rate the diffculty of my shorter races. I don't think this calculator puts enough emphasis on weekly mileage.
If this calculator is spot on for you, I would bet that you're leaving plenty on the table with training.
I guess I'm the only runner that it had a too fast of a prediction?
It was about 10 minutes too fast based on my 5k and half marathon prior to the marathon.

It works for Paula, but she was drafted around to 2"15
Calculation from tables on malmo's site gives
28'00 = 61'18 = 2"09'12
27'00 = 59'12 = 2"04'57
the 2"02'57wr
( run on berlin which is not 100% flat )
= 26'31
58'16
the M wr is now intrinsically better than 1/2M
For me it was about a minute slow. Then put in what would happen if I dropped 2 min off my half marathon time, 1 minute off my 5 mile time and added 10 miles a week and it said I'd run 1:36...
