qSpine calculator check

[ScreamingPotato]

Wife needs a new set of arrows so I went ahead and paid for the app and plugged in all the info, this thing's coming back with a 600 and is showing even that to be almost too stiff, which strikes me awfully weak for her setup but maybe I'm just off. I figured maybe I could get some input here and a quick sanity check from the RS crew. Easton chart puts her at "500-400" which is also pretty vague.

qSpine gives me very similar output using the inputs you listed above and the default weight on string values (8 gr peep, 4 gr d-loop, 2 gr nock set):


FWIW the spine calculator on Victory's website recommends 500.

Thank you for the link, definitely more confident with that than some of the other charts I've seen.
