I don't like the words novice and light, when you get more experienced in turfing, so my suggestion sounds like the following...
Rank
1 = light scout
2 = light traveller
3 = light explorer
4 = light explorer
5 = light adventurer
6 = light seeker
7 = light conquistador
8 = light zoner
9 = light turfer
and then on again...
10 = novice scout
11 = novice traveller
and on again...
18 = experienced scout
26 = advanced scout
34 = master scout
42 = grandmaster scout
49 = grandmaster turfer
the highest Ranks is fine and specifik så they are good as they are now
