It is advisable to only spend Cartographer's Chisels on higher level maps, as the more item quantity on a low level map translates to negligible gains. Furthermore, since Chisels are relatively uncommon, it is usually recommended to only spend them on normal maps rather than magic or rare maps. Also, once a map is 20% it stays 20% even when scoured or changed in any other way.
