Do I send to RSC???

[Anamelistic]

I just acquired a 2nd hand 114060, great shape all around. Dated 2017 and after timing it for 2 days it seems to be +3/spd after being on wrist all day and then dial up during sleep. Im glad its running in the positive but I am coming from a Tudor 79230B that had been running < -.03/spd which I expected something close from a modern Rolex model. I take great pride in the precision of in-house automatic movements that are "Officially Certified" and expected a bit more from a "Superlative Chronometer"

I guess my question is as follows: Do I get some more wear out of it and then send it in while getting an appraisal from Rolex at the same time ( I think they still do that) OR Send it in ASAP before I become even more attached and wont be able to part with it???
