I'm having trouble determining the meaning of rule 5D1, which requires competitors to have data spanning "at least one variable range listed in 4.Part I.a".

To me, a variable range is a high value and a low value and all of the possible values in between for a given variable. For example, 60 degrees to 90 degrees celcius. However, the variables listed in 4.Part I.a are just the time and the possible volumes, which means that for Division B, the only acceptable variable range they can "span" is the volume range from 75 to 125. Why not just say that Division B must have data spanning from 75 to 125 mL? It seems extraordinarily confusing and unnecessary, especially considering Division C could span the "20 to 30 minutes" listed in 4.Part I.a. Furthermore, teams that are only preparing for regionals don't need volume measurements at any volume except 100 mL.

I know this isn't the place for FAQs, but I believe that portal hasn't opened yet on soinc.org. Any other interpretations about what this means, and what must be done to span "at least one variable range"?
