optimal split differential between 50s in 100

what is the optimal differential between the first and second 50 on a 100 yard short course freestyle? The first 50 benefits from the dive and the relative freshness of the swimmer; the second 50 requires two turns and contending with lactate and fatigue. Is it better to go all out and try to hold on, or save a little for the end? Say you can swim an all-out 50 by itself at 25 seconds. How would you ideally swim the 100? Example: 25.5 then 28.5 for 3 second differential and a 54.0 or 26.0 and 28 for a 2 second differential and a 54. Which method do you think is best?

    So there was actually an error in the formula as you originally stated it. It's actually twice your fastest 50 times plus four seconds, not three. I was waiting for the hole poking. From an engineer no less! :doh: One second off of best 50...then 2 more seconds over that time...is four! I guess that's where the .50 fudge factor came about. "It's actually twice your fastest 50 times plus four seconds, not three." Thanks kirk. :)
