Turret Height and Bonuses

[Lehanius]

Hello, I recently bought the game and have enjoyed it a lot so far.

However, after many, many hours of gameplay, I can't understand and haven't found anywhere an explanation on how the turrets height works. I even opened the Mod Editor to look up for some enlightening info.

It seems that height bonuses change upon target acquisition, which makes sense, assuming it is recalculating the height above each target. It seemed a bit confusing but now I think I got that figured out (please correct me if I've misunderstood it). Though, I have built some towers at really high places to get a big bonus but it seems that the bonus is capped to 50%. I built two watchtowers at different heights but I never saw the bonus go above 50%. It was very disappointing, it would be nice to get a range bonus at least. It gets kinda shallow on basebuilding strategy if my watchtower gives the same bonus wherever I place it, specially since it is very rare to find some land that is both high and rich on resources - which would bring opportunity for very interesting trade-offs.

So, have I got it wrong or are turret height bonuses really hardcoded to cap at 50%? Is there any way to increase it, even if it means modding the game?
