conduit length confusion

i have seen a calulator for mpcnc at

but the added parameters to the conduits are different than from the vicious site calculator, ie for eg ,for the x and y conduits the added lenth to the desired length in vicious site calc is 10.4 incheswhere as in the mentioned link it is 11 inches.

pls coment regarding this. which one is reliable to use.




Use the one from the site,, that other one was made a few revisions ago by someone else.

Where did you find the link to that other one?
