Well I finally tested my home made leakdown tester today.  Here are my results:
cylinder # 1 - 7.5% leakdown  (compression 165)
cylinder # 2 - 6.25% leakdown (compression 180)
cylinder # 3 - 17.5% leakdown (compression 170)
cylinder # 4 - 13.72% leakdown (compression 175)
 
Motor is a 1.9l with 134K miles.
 
Now I have to figure what all that data means.  If anyone has any thought please let me know.  I might try it again tomorow to double check.
