In reply to Leeds Andy:
useful stuff, but that's a lot of credit card floating about. fiddly.
How about it all on an A5 laminate, with the gradient calculators at each corner (so that you can apply to map) and more info on the pacing....only per hundred meters gives you lots of sums to do. I know it is easy enough to to work out say 380m from a 100m pacing rate but anything that eliminates errors in the field is good. (in the same way that you have broken down the timing)
Think A5 is too big? Consider the size of the map: even folded it is rarley if ever less than A5. You can use both sides, one for nav aids, one for avalanche aids.
Mag variation numbers need to be in bold, or remove the background logo.
