I am not really liking sudden death at all.
With two reasonably skilled teams, SD is often a tactic. Teams often wait until SD to start that rush.
Its mosttimes the team that camped 5 minutes before SD to accumulate enough evo/credits that wins (human camping in their base, aliens camping around human base).
I have seen it often, giving a good skilled and teamplay able human team, a simple 6 bsuits with lucy attack on alien base in SD finishes the game (giving a server with standard bp). You just have to make sure that you have the credits to buy these items just before SD. Only a human team that does not attack in the beginning of SD is a loosing human team.
So statistics are only useful when you count in what tactic was used
What the statistics are for not skilled teams or teams that us wrong tactics I think should be ignored.
But since SD can become a tactic, it changes the game for those last 5/10/15 minutes before SD. Usually its a bore, cause both teams are just trying to save up on credits/evo for that SD rush. Most experienced players will stop taking risks before SD.
My suggestion for making SD more usefull, is not improving game play in SD so much (free armoury), but to make it such that it is unattractive to wait for SD.
Maybe a random or killcount based autokick of players every 20 seconds

My 2c.
edit: wah, i think i am starting to like that autokick in SD idea
