Just in case this is helpful for others, as we just spent an embarrassingly long time wondering why our fit was so bad. You need your chart photo to be oriented with the white square at the bottom left (as on the video) or else it won’t work properly!

(We also got briefly tripped up by the fact by that the name for your cone catch model needs to begin with a letter rather than a number…)

Chart needs to be in same orientation as video!
