Adjustment of MA1 and Logan model start-time t*, showing the goodness-of-fit metrics for Logan (Pearson r2) and MA1 (1 − rSEE) as well as the trend of VT values (blue and green lines) for both models compared to the 1TC reference (red line). t* = 5 min produced the highest Logan r2 with corresponding VT = 18.2 mL/cm3, and MA1 VT = 19.8 mL/cm3 which was close to the reference 1TC value of 20 mL/cm3 (black diamond)
