Compression Check Results ??? Somone exlpain

I went and had my compression tested today b/c I was told my engine was 33,000 miles old but Ive been having some injector leakage and hard hot starting. My starter is on its way out and I think my alternator is too b/c Ive had to jump the car a few times recently. I asked the place that tested my compression if that mattered and they said no. They used the same compression checker as the one in the FSM but didnt disconnect the crank angle sensor. When I left I had to pull over and swap my leading and trailing wires b/c they were put on wrong. Here is a pic of my low compression diagnosed readout.

Whats everyone think?

for clarification on the crappy pic of the last one...the lowest is 5kg/cm2 and the highest is a little under 6

My car pulls hard. The only reason I suspected low compression was the starting issue. Once its started it runs great.
