There is a range below for vertical refresh, 50-160, how do I know what is an acceptable range if I were to extend this?

You should read the documentation for the xorg or XFree86 distribution,
whichever is used by Fedora, and consult the manual for your monitor for
the h and v sync ranges.

NAME
cvt - calculate VESA CVT mode lines SYNOPSIS
cvt [-v|--verbose] [-r|--reduced] h-resolution v-resolution [refresh] DESCRIPTION
Cvt is a utility for calculating VESA Coordinated Video Timing modes. Given the desired horizontal and vertical resolutions, a modeline adhering to the CVT standard is printed. This modeline can be included in Xorg xorg.conf(5) OPTIONS
refresh Provide a vertical refresh rate in Hz. The CVT standard prefers either 50.0, 60.0, 75.0 or 85.0Hz. The default is 60.0Hz. -v|--verbose Warn verbosely when a given mode does not completely correspond with CVT standards. -r|--reduced Create a mode with reduced blanking. This allows for higher frequency signals, with a lower or equal dotclock. Not for Cathode Ray Tube based displays though. SEE ALSO
xorg.conf(5), gtf(1) AUTHOR
Luc Verhaegen. This program is based on the Coordinated Video Timing sample implementation written by Graham Loveridge. This file is publicly available at <http://www.vesa.org/Public/CVT/CVTd6r1.xls>. CVT is a VESA trademark. X Version 11 xorg-server 1.12.4 CVT(1)
