Do lower ranks of skills affect higher ranked ones?
For example, there are 9 ranks of "Cruiser Captain". Do these help you as you move on to Heavy Cruisers and so on, or is the effect completely lost when you move to the higher tiers of ships?
Also, for skills with different ranks like Medical Tricorder I and Medical Tricorder II: do they both work when trained by the same officer? (Say, on different cooldowns so you can get heals more often.) Does putting points into Medical Tricorder I make Medical Tricorder II better at all?
I have also wondered this. I think like Cruisers in the description says it applies to ALL CRUISERS. But if you put points into Heavy Cruiser it says it only applies to heavy cruiser class ships. So I would presume it would have no impact on say Exploration Cruiser or Battle Cruiser. Can someone confirm this?
