Majority of HQ exp, as you have noticed, is from the Boss node, enroute nodes have insignificant HQ exp.

This only works pre HQ Lv 80 as the 80 tier contains a nuclear sub on the first node.

Also, there's no reason to bring a sub because subs cannot hit subs. You are better off bringing 6 ships you want to level and farm 3 nodes in if you worry about HQ.
