Those numbers are awful. Looks like your top rings are shot and there is a potential head gasket issue between the 2nd and 3rd cylinder. If a leakdown test yields similar numbers, I would recommend a rebuild or, at the very least, a piston ring, head gasket, and valve seal replacement.

I agree. Looks like your rings are fried, and you might have ringland damage...and possible headgasket damage.
