as i used the same source data we should not have such a discrepancy. will review in detail tomorrow.
I've used totals for Europe from the wikiposts on TMC and US estimated sales from InsideEVs.com to arrive at other than US and Europe sales. This method yields data which differ significantly from your method. According to my method Q1 other are 8,010, while Q2 other - 6,773. My method yields higher midpoint projection on deliveries - around 28,500. It is summarized here and then corrected numbers are included here.
