Check if polygon was clipped excessively during offset

[MatthewJolly]

I am trying to offset a polygon multiple times, and sometimes this results in an offset big enough that the resulting polygon contour no longer matches the shape of its parent (as some overlapping regions were clipped out). Is there an easy way to check if this happened, so that I can ignore those polygons? In essence I only want the offset polygons where the contour mostly resembles the shape of the original polygon.

This paper mentions offsetting the result polygon in reverse and then checking the areas, but when I try this I get polygons that are different enough where the area calculation doesn't work (because the reverse offset polygon differs from the source polygon enough to be unreliable).

For instance, given this polygon, which was offset 4 times, I want to eliminate the red shaded offset polygons.

Is there a simple way to do this?

I'm not sure if this suggestion below will be entirely reliable, but ...

For each offset iteration:
  get the bounds of the path and shrink it by the delta value (rec1)
  perform the path offset
  get the bounds of the offset path (rec2)
  compare rec1 and rec2 and if they're sufficiently different then break
