I'm a bit confused about the (uncharacteristically) complicated computer rules in Traveller - which generally seems pretty straightforward otherwise.
Specifically: a character uses the Expert Navigation/3 program. As I read it the following cases arise depending on the skill of the character:
no skill: Roll at +2 (program rating -1)
0 skill: ditto
1 skill: ditto
2 skill: computer no use! roll against own skill at +2
3 skill: computer no use! roll at +3 using own skill
4 skill: roll at +5 (own skill +1 for having an appropriate program at a lower level)
This seems a bit strange to me - that if you have the same or one less skill than an expert program's rating, that it's useless to you, whereas if you are much worse or better, then it can aid you. I'm concluding that I've misinterpreted the rule - so please put me right!
