...uh, a "baseline" is a 'starting point' from which to compare 'new' data against, it's NOT used for trendline analyses!
...it's the "starting" line of a race, not the one-foot graduation marks around the field!
...I understood that he wants to establish his "starting" point mpg, so that he can accurately determine his ħmpg results, ie: what "worked" (produced +mpg) and what "didn't work" (produced -mpg).
...to determine if his rate of changes (ie: trendline!) is linear, curvilinear, etc., now *that's* when he'd need about 30 data sets.
