V2: zero wind, best flights from #1 were to the fence line past White House. 2.0km distance, 930m alt, pulling at 150m and substracting 100m for the start gives L/D of 2.9 (same as at ITW).

As a side note, 6m/s tail wind adds about 300m distance or 0.5 L/D at this site ;)

Prodigy: #8 to LZ, 1.5km distance and 930m alt, pulling at 100+m, L/D comes to about 2.1. The wind is not a big factor at this site.

bsbd!

I think this is underestimate. L/D can be more accurately estimated by integrating the wingsuit equations and trying to match the horizontal and vertical distance. Using this Excel spreadsheet, for 6666ft horizontally and 2600ft vertically L/D comes to about 3.5.

5000ft horizontally, 2770ft vertically: L/D = 2.5
