Ok, so I average 54 paces over 100 metres, which is 4mm on a 1:25k grid.
This is a simple enough sum, to work out any 25metre increment, {X} I simply multiply 54x {X}
So if X = 700 metres [28mm] I can multiply 54, by 7.00 = 378 paces.
So its easy enough to double this, to write a pace card, for a 1:50k grid, then double that again, for a 1:100k Grid.
But Ive just bought a harvey map, which has a 1:40k grid.
So, I know that over 200 metres, which is 5mm on a 1:40k grid, my average pace is 108 steps. [Twice 54]
To work out my paces with the 1:40k map there seems to be an additional calculation I need to perform. Namely to divide by 2.
[Because the pace chart on the 1:40k map rises by 40 metre increments, the figures jump from 80 metres to 120 metres.]
So to work out my average pace over 240 metres, I need to multiply 108 by 2.40 = 259.2 / 2 = 129.6 paces.
I think thats correct, just double checking.
Thanks.
