He means the map levels of each material. When you go to auto levelup, it has the columns: Location, LEVEL, Exp, Drops. the 101 for Wolf Claw is the map level for it.

As for EXP Tech, that's not entirely true. My guildmate and I were farming the same materials. We were on the same royal challenge boss, same rank, but he made 4300 EXP per hit whereas I only made 4100. He had a higher EXP tech than me.
