'73 911 E compression test

[tmctguer]

i have a '73 911E with 2.4L MFI. the engine has approx. 60,000 miles on it. i did a compression test and here are my results:

cyl. 1: 142
cyl. 2: 155
cyl. 3: 150
cyl. 4: 155
cyl. 5: 153
cyl. 6: 155

how do these results look? should i be worried about the low reading of #1 cylinder?
