The use of 1:15000 scale

[NeilC]

A few weeks ago we had a brilliant event using a 1:1000 school map. Really wouldn't have worked with 6cm control circles.

I would have expected the symbols to have changed size in proportion to the map scale.

Symbol size increases between 1:15,000 and 1:10,000 in order to make the symbols easier to read for old people.

Maps produced at scales of 1:5,000, 1:1,000 etc are done so in order to get more detail onto them - eg maps of school grounds. Increasing the symbol size would defeat the object of this.

Symbol sizes for 1:5000, 1:7500 & 1:10000 should all be the same - 150% of 1:15000.
So if you are changing scale from 5000 to 7500 don't check the enlarge/reduce box.

What is the logic in this?
I would have expected the symbols to have changed size in propotion to the map scale. Seems simple and logical to me

I thought that if there were (say) 1:15000 maps for the younger runners and 1:10000 maps for the older ones, then the latter were straight enlargements, i.e. with bigger symbols?

That is correct, but if you enlarge to anything bigger than 1:10000 you still leave the symbols at the 1:10000 size (150% enlargement), for the reasons that sjc and NeilC have given above.
