"Anyway, does anyone else find this tedious like me?" Yes but its some of the basis of my pay.

"Does anyone else use the WRC-107 calculator?" Yes

"Does anyway else think I'm an ungrateful malcontent who should be glad that never had to do any of this by hand and I should just shut my trap ?" Maybe some people will (not myself), but factually if you look at this program it has undergone constant improvements and refreshes.... Sometimes the effort has fallen short of the mark (3.24 to 4.0 comes to mind) and other times the changes have been brilliant. But COADE does value comments on improvements.... They may not be able to act upon all of them but I am sure they will read your suggestion.
