Depends if you count a minimum of 10% "regularly"?
From 2003: "After the New York City raid that killed Alberta Spruill, Police Chief Raymond Kelly estimated that at least 10 percent of the city’s 450+ monthly no-knock drug raids were served on the wrong address, under bad information, or otherwise didn’t produce enough evidence for an arrest. Kelly conceded, however, that NYPD didn’t keep careful track of botched raids, leading one city council member to speculate the problem could be even worse."
We’re not talking about the same thing are we? This conversation is specifically about where dispatchers are sent after a person makes a call requesting law enforcement, giving their address.
Although I think it speaks to the general competence of the US police that they can't get the right address even when they've spent days/weeks organising a raid - I wouldn't necessarily trust them to get it right on a fast rollout on a SWAT call.

There's a whole bunch documented here (where I got the quote) - https://www.cato.org/sites/cato.org/files/pubs/pdf/balko_whi...
