I think you entered the STA data wrong in the calculator. Didn't you reverse them?

If you've settled on a horizontal bb-to saddle offset (aka effective STA) as unterhausen mentioned, then reach becomes the critical number to look at, although it's slightly altered by frame stack. When hta and chain stay length are the same, I like to compare wheelbase #s, but those figures are apparently omitted.

73 HTA w/70mm offset? Interesting geo.
