Another LB7 Balance Rate Quesiton

I recently bought my first diesel- 2003 LB7 CCSB Sierra. I've been trying to save and set aside money for when the injectors go out. I was able to get the balance rates on them and am wondering if you guys can tell me if they are reasonably within GM spec. I believe they look fine but want to confirm. The truck has 185k miles. Injectors changed somewhere around 110-115k from previous owner. Fuel mileage is 19-20 @ 70mph. No smoke or haze whatsoever. Thanks in advance!

Cyl 1- 1.7
Cyl 2- -0.2
Cyl 3- -0.3
Cyl 4- 0.1
Cyl 5- 0.1
Cyl 6- 0.1
Cyl 7- -0.8
Cly 8- -0.4
