Seems like a smart move.

I think a summary would actually be very valuable in this case - perhaps a  
note about one or two of the key temparature levels, and an idea of how  
far the others vary. Shouldn't involve a lot of code for that...

As well as helping the screen reader users, it helps to have a summary of  
complex information, and this table is enough to be confronting for lots  
of people. And the summary will be useful for others of us who don't admit  
we find the table complex to decipher, too :-)
