Chuili's time proved Daniel's table. It converts equally. But, you are right. The table assumes equitable strengths which aren't always even depending on placing in the cycle. The table helps illuminate weaknesses, if you can call them that in a case like Bumbi, that can be worked on.
Not my guide, but Daniels', and it works out pretty closely in most cases.
By the by, Daniel's table says 1:54 equates to a 4:13 mile or 4:11 1600, I think pretty close to what he ran at state last year. His 8:49 two mile, according to the chart, equates to a 4:07, probably what he would have run fresh. All that for what it's worth.
