The forces against a frac plug during the frac is equal to (up to) 10,000 psi times the area of the casing ID. For 5.5" 20# casing this can be up to 200,000 lbs. When milling out the weight on the bit can be up to 10,000 lbs, much less than what the slips are designed to handle.
Balanced-plug method. Basic calculations - Better Well ...
It is common practice to slightly under-displace the plug (usually by 1–3 bbl). This practice avoids control fluid flow back on the rig floor after placement and allows the plug to reach a hydrostatic balance. Once the plug is balanced, the pipe is slowly pulled out of the cement to a depth above the plug, and excess cement is reversed out.

How to drill out cement from a well casing? : AskEngineers
The proper way to plug a well is to set cement plugs throughout the wellbore in critical areas (above the top perfs and around and overpressured zones). Cement is then circulated from about 300' to the surface and the wellhead is removed. At least in Texas, current regulations state that operators basically have to make it appear as if the well ...
