camshaft deviation analysis

[j.fro]

I hooked up my Durametric today to look at camshaft deviation specs. Do these look good? Is there anything else I should check?
2000 Boxster S, 167,000 miles, original IMS:
Bank 1: -5.63
Bank 2: -6.5
remained unchanged regardless of RPM

1999 Carrera 4, 77,000 miles, just replaced IMS w/LNE:
Bank 1: -6.56
Bank 2: - 4.39
remained unchanged regardless of RPM

I was looking to get air-fuel ratios, but couldn't find that function in Durametric... am I missing something?
