than n seconds on your CPU. Generate cash that takes n*k seconds. This naturally evolves to take account of improved speeds _and_ variance without tweaking being required after setting an initial value (though the owner of a very fast CPU might have to downgrade the default n, and a very slow CPU upgrade k).
