Yes, and 120 was chosen AIUI specifically to allow finer grained control later, the only reference to 120 is in the prose description, the actual this spec part of the page your referencing makes it clear it's just an int. This spec is now removing that possibility of finer grained control, and sticking with a magic default number, so even for wheelDelta I don't think it's right. Cheers, Jim.
