Nacra F17 Uni spi (NI17R) NF17 66.7 69.0 68.3 66.6 65.0

First numbers is base, then 0-1, 2-3, 4, 5+

So, if you have a chute and were racing in Beaufort 0-1, 69 would be the correct number. Since you say they didn't use wind corrections, they did you a favor since your base number is 66.7 (if you have a chute).
