Did I install the timing belt correctly? S60 2012 t5

[Syoma]

Hello! I replaced the timing belt and rollers along with the water pump for the first time. I followed the instructions, and the engine started without any problems. However, after checking the parameters in VIDA, I have some doubts. Specifically regarding the values: camshaft adaptation exhaust is 50.6, while the manual allows 54 CA ±8, but I’m still a bit concerned about this; the camshaft shifting angle — both parameters at idle — fluctuate in real time by about 4 units above and below the nominal value. Could it be that I made a mistake during installation? I’ve been driving for quite some time now, no new errors have appeared, and the car drives confidently, basically just like before the replacement.

Thanks in advance for your help!
