How much leakdown before power loss is felt?

[destrux]

I ran a leakdown test on my engine and came up with 10%, 30%, 10%, 30%. The engine was cold (75 deg F). Is this enough wear to cause a noticeable power loss, or should I just not worry about it yet? I can rebuild my motor, but I'd rather put the $1000 or so into saving for an AWD 2g or (gasp) an SRT-4.

Please dont get an srt 4 they are FWD and go no were when the power is applyed. I would save up for a nice clean AWD 1G. 30% is alot on a leak down.
