To answer you question: All programs shave. Some intentionally, some unintentionally.
Unintentional shaving comes from loss of tracking, for various reasons. My personal guess is about 1-2% of all tracking is lost on just about every program out there.
There is also an unintentional shave where a surfer that has already joined a program in the past goes back to the site again through your links... with many programs offering a "all sites for one price" type deal, some of them won't pay for a returning customer as they would for a new customer. This is also an issue on programs that pay once for a user to signup "lifetime"... so even if you send him back today and he does something that makes money, the original webmaster and not you gets the credit.
Intentional shaving comes from everything from hardcoded links, links off, email boxes that don't pay, intentionally dropped affiliate codes, etc. Even programs using the vaunted NATS or MPA can shave you, by manipulating how your traffic moved through the tours, and such.
Overt shaving includes things like popping other sites over the top of the tour, or paying companies like Zango to run popups / filter traffic, abusive geo-filtering, etc.
When you combine all of this with programs that all use different methods for counting raws, uniques, and so on... it is almost impossible to compare program A to program B... but after 10 years of doing this, I can tell you that they all shave, just some are robbing you and some are just "oops".
