Not. At least when I do it. Here's what I get after recalcing your example.

#+TBLFM: $5=$4*0.83;Df2Maybe I have a different mode setting or something. You seem to have
the $4, or 1:09, being interpreted as 69, but I have it being
interpreted as a calc fraction, i.e., 1/9 = 0.11111111. So 0.83 *
0.111111 gives me 0.9259, which rounds to 0.9.

waiting for vi to duplicate that functionality.
Thanks for taking the time to look at this.
