Spread the Daf!
there's 100 cents in a half step.
so you can see that 10 to 20 cents would be off by enough to be very noticable.
As a piano tuner, I've learned that most people can't really hear a problem of just a few cents though some can.
For instance, I'll have people tell me that they want the piano tuned to the European standard of A=442 instead of the common A=440. Fact is, that's such a small amount that VERY few people will hear the difference although I'm sure some will pop in here saying that THEY can hear it. And it is possible ...... I can hear it ..... but I tuned 3 to 5 pianos a day 6 days a week for 30 years. Redgrdless, once you get past say, 5-7 cents off, it starts to get more noticable and 10 cents is gonna be obvious to most anyone.
As for the tuner ...... you'll need to check it against a standard .... either a tuning fork (easy to get hold of) or against a higher quality tuner.
It's certainly possible that yours is acceptable but cheap tuners do vary a suprisingly large amount.
