Worcester County tone outs?

I see the Worcester wiki has recently been updated to add in tone-out listings.



Worcester County (MD) Fire - The RadioReference Wiki



Some of the tones listed in the wiki are different from the tones I have recorded. Did Worcester just recently change their tones or are those listed in the wiki incorrect? I just noticed the update to the wiki a few hours ago but I'll be checking Worcester to see if there has been any changes that I can confirm or deny.
