(After doing this fix I can't say that I'm too thrilled about this method - or
even pair of methods. Too overly generically side-effecty...)

Bringing the implementation closer in structure to

Yes... When this will be done will probably depend on the outcome of the above.
(I.e if we need to add code to measure this it'll probably be easier to
restructure first...)
