Fast live rebuy turney - should I even bother?

[Big Bend]

$20 cash = $3000 turney chips. Can buy up to $6000 anytime at or below $3000. I always buy the max $6000 in chips ($40 cash). Blinds start $100/$200, then go up every 10 minutes. Can rebuy the first 5 levels.

100/200
200/400
300/600
400/800
500/1000
break time, color up, one last rebuy for those wanting it
1000/2000

Soooo.. my question is, after like 20 minutes the max rebuy only gets me 10X the big blind. Is it ever correct to keep rebuying with such high high fast blinds? I mean, even the first level I'm only getting 30X the blinds to max out on chips... by the time the break is over my max rebuy is only 3X the big blind.

Obviously its an ICM all-in fest pretty quick in this turney... just wondering if my edge with ICM knowledge makes it +EV to keep rebuying even when the blinds are so high.

Thx... BB

I played twice in a similar tourney with t10000 to start and 100/200 blinds with 15 minute levels. It was very discouraging and I found I needed good cards or good luck very quickly. I didn't find it enjoyable at all.
