Too long? or not too long? That is the question!

The link is for the print screen i made describing my personal musings about length of underground belts.
The "Basic tier" / "Gray Belts" made my preferable settings for underground belts unachievable.
It is nothing which is making a game unplayable for me but the middle setting i decided to go because of right side one being impossible (in my small knowledge) to set is somewhat overpowered in term of length.
But on the other hand i play the pack with 30Sience packs + SpaceX + Payloads + BobAngel so all the length will be needed because my main bus will be massive fat one Kappa :D
Please feel free to comment on the three settings i show on the screenshot
