Thank you for such an elaborate answer. My math skills are pretty basic, so I won't pretend I understood all the facets of your explanations. I'd appreciate it if you could state a solution in some lament terms. It appears that the logarithm option is a feasible one, but it'd be great if you could provide an explanation on how to apply it to the USD/Pound example listed in my original post. Thank you.
