Scanning the export for structural issues before running any analysis — a few things need clarification first. What I found in the scan: Kattaqo'rg'on–Samarkand: Complete row. 450 rides, $2,100 revenue, $600 cost. Tashkent–Samarkand: Complete row. 120 rides, $3,500 revenue, $1,800 cost. Bukhara–Samarkand: Revenue and ride count present, but Fuel/Maintenance Cost is corrupted/null — this is a critical gap since it's the route also flagged with 12 of 14 total complaints (late arrivals, bad roads). General Expenses ($450 hosting + $300 marketing = $750/month) are listed as a lump sum, not broken out per route.
