More Great Moments in Questionable Editing

From an article in today's Times about the Secret Service-Colombian prostitutes scandal:

Senator Susan Collins of Maine, the senior Republican on the Senate Homeland Security Committee, who was also briefed on the investigation by Mr. Sullivan, said a total of 20 to 21 local women were brought into the sprawling beachfront complex called the Hotel Caribe. She said that some of the women accompanied Secret Service agents and that others escorted members of the military, which is conducting its own investigation.

See it? A "total of 20 to 21 local women"?  I get that there may be some uncertainty as to the total number of Colombian prostitutes--or Colombitutes (Prostilombians?)--involved, but shouldn't that be "20 or 21 local women"?  Or might the Secret Service somehow have smuggled in, say, 20.8 women?
