So I cut this pattern this evening. 5/16" hardwood, FD #1 polar blade, glued directly to the wood, tape added as needed to support the pattern (next time I'll cut the inside first, outside last). Found a feature in Inkscape that will (I think) measure the length of all the lines in a pattern:
File in svg mode; import, ungroup, trace bitmap (only use the bitmap image). Select the pattern then; extensions > visualize path > measure path (measurement type, length)
Inkscape said that the total path(s) length was 242.78 inches (when I enlarged the pattern and remeasured the length increased proportionally). To compare, Splat Cat, came in at 412 inches.
I took 90 minutes to cut out the pattern, so 90 x 60 = 5400 seconds / 242 inches is 22.31 seconds per inch cut. (Yes, my brain melted about then).
The whole point of this exercise is my attempt to extrapolate how long it should take me to cut an unknown pattern. If I can get the extra big panels to work it's something I'll need to know.
Here is the item:
