Yes, there are more than four between 5.90m and 5.97m. I failed to include Walker, who makes five at 5.90m or higher. I haven't included indoors on any highlight of the 2012 season. Lavillenie and Otto are two of the five who vaulted 5.90m or higher outdoors. And, I didn't include indoors for the vault comparisons between 2012/2011/2008. However, I do appreciate your disagreement, as it brought Walker deservingly back into the fold.
