Projection is formula-driven and follows workbook equations using superbase damage and class Power/Knowledge.
Formula path: F = ROUNDUP(Superbase * 0.02, 0), Tooltip(+L) = ROUNDDOWN(Superbase*classStat + F*classStat*L + F*classStat, 0).
Project from your current enchant level to any target level from +0 to +26.
