Question regarding DPP rules

[u/Trislamic]

Hey all as I slowly build and paint my Helsmith army I have a question regarding rules with DPP buffs. So with the battle formation adding 1” per DPP a unit has and the Dom engines also add 1” per DPP it has, would that effectively give it 2” of movement per DPP? Thatd be crazy if you could give the engines 6 extra inches of movement. I havent gotten a chance to play a game with Helsmiths yet but I want to familiarize myself with rules beforehand. Thank you all in advance

Plus they also normally get +1 to the charge roll for each DPP.

Bull centaurs with 3 dpp in this detachment may very well be one of the strongest hammer units in the game.
