2. Medium - Squared root natural logarithmic --> totalPrice / sqrt(natural logarithm(unitPrice))"
3. High - Base 10 logarithmic --> totalPrice / base 10 logarithm(unitPrice)"
4. Very High - Natural logarithmic --> totalPrice / natural logarithm(unitPrice)",

1.03 - added option to use player level in calculation if actor level is lower than player level
1.02 - try to apply GMSTs changes immediately instead than on next reload

Note:
if you have problems with upgrading try deleting the old Data Files\MWSE\config\abotSmart_Merchants.json file
