Before another 7 billion yrs ago ( or total 14 billion yrs ago ) the expansion rate was ( 17 x .85 ) = 14.45 km/sec/mlyrs.
So 13.7 billion yrs ago the expansion rate was not zero but about 14.45 Km/s/m

You'd have run the equations of general relativity to come up with accurate results. I have seen the Friedman equations used, and of course Hubbles constant.
