What "limit" is this you are referring to? The prescribed one exercise a day was of no specified length. If one is truly to minimise time - and take that word and meaning literally, as you seem to be doing - that means zero. None. Zilch. That is the minimum - or if you do not wish to consider zero a number, then make it one second. Anything above that is no longer a minimum.
The more sensible discussion was about what is reasonable under the circumstances, and that will vary by location - three hours on a lonely road in the Scottish highlands is not the same as three hours tooling around London.
I was quoting someone else, I didn't refer to any limit.
Your definition of minimising makes no sense for it amounts to not doing it at all.
