James--
One other thing that you're forgetting: While offensive order-reversal is an extreme and drastic offensive strategy, truncation needn't even be an offensive strategy at all. Truncation can be done just to deter offensive order-reverssal. In fact truncation can be done for no strategic reason at all. Usually truncation won't have a strategic motive. Some people will truncate because there are just people for whom they don't want to vote, from principle or due to distaste, etc. And people will truncate because they don't know much about all the candidates, or because they just don't want to take the time, or don't want to take the trouble, to rank all of them. Maybe the merit differences among their lower choices aren't so important to them. Studies have shown that to often be the case, that perceived utility differences between lower choices tend to be less. So it's not surprising if some don't rank all the candidates.
So your effort to equate truncation with offensive order-reversal won't work.
As I said, there has always been much truncation in our EM polls. Not strategic truncation, just truncation.
In those polls, the SFC and GSFC compliance of wv was there to assure you that that truncation that always takes place, in the event that it caused a circular tie when there's a CW, as could happen, wouldn't be a reason for you to need to do other than rank sincerely. If you've taken part in EM polls, or in the wv polls at websites, such as the masquilier.org website, then you have benefited from the SFC and GFSC compliance of wv. That SFC and GSFC compliance makes wv more stable than other rank-counts. In particular, more stable than other pairwise-count methods, because innocently intended truncation won't mess up the result, cause a CW to lose, cause a majority wishes violation, or create a defensive strategic need for doing other than ranking sincerely.
