Appendix B says to use both synoptic and downdraft for region III. How do you apply this? Does this mean do 2 calculations for every line and use the worst case for your design? I'd appreciated hearing any thoughts on this.

Downdraft always gives a larger value for SRF (see graph) so do you assume that will be the most conservative result and only do one calculation?
