You might be surprised at the number of voluntary surveys turned in. No doubt the odd WMU could be short on responses one year but overall, the response is better than the 10% you say are needed. When you look at the trend over 6 or 7 years, I'm sure the odd WMU that was short on responses one year balances out.
