I have a program which specifies commencement and completion activities, we'll call them "A" and "B" respectively. It then outputs the percent of duration between them that hasn't elapsed:
Percentage of the way from A to B: 13%
The "of the way" feels very uncomfortable and unnecessary yet without the phrase I like it even less:
Percentage from A to B: 13%
Is there a way that I can more clearly state that this is the fraction of the total time between A and B that remains?
