yep i write few values while investigate. the error is low, but for what i need need very low. The origin ins’t far.
575 / 746.548 / 213
574.287 / 671.045 /214.150
574.104 / 671.588 / 215.150
i think the cause its the pawn movement, with that delay seems fixed.
except if i jump or while falling and press the key for teleport/set location/e.tc. the error its more big (anyway nothing drastic) . i think i must disable that possibility in my proyect. 
anyone known if its bug or normal issue? must report bug?
