I think we are all missing the point here. Bashareholder has taken the time to construct a convincing looking spreadsheet and put it online. It is attracting all sorts of outraged huffing and puffing, and has therefore acquired the status of "fact".
That it is complete tosh is recognised by those who wish to see, but what of those grasping at straws to bolster their flagging morale?
This is a classic tactic by BASSA. Put out a suspect, or even totally fictitious "fact" and et the troops get all riled up. Before long no one even dares to question the "fact", it simply becomes the received wisdom - "truth" in la la land.
I wouldn't be surprised if, by tomorrow, some bright spark has argued that cc have already taken a 4.1% pay CUT and therefore further concessions are unnecessary!
