BiND, you have every right to be confused with the Covid points allocation system. The overall points in the BBC & PR tables are correct but here are the issues:
In the case of Quins & Saints you omitted to include the 2 points ‘loss’ for Covid cancelled games (1 each) hence why you are two points off for each.
For Newcastle, you actually spotted an error in the BBC table as Newcastle only secured one BP (a LBP against Exeter) and not two as shown
(PR table is correct). Also similar to the above you omitted to include the 2 points ‘loss’ for their Covid cancelled game against Saints last weekend.
I tried to show the full breakdown below:
W/D/L - denotes results from games played
CW/CL - denotes Covid ‘win’ or ‘loss’Harlequins: W5 (20), D1 (2), L2, BP4 (4), CW0 (0), CL1 (2) = 28 points
Northampton: W3 (12), D0 (0), L3, BP4 (4), CW2 (8 ), CL1 (2) = 26 points
Newcastle: W4 (16), D0 (0), L3, BP1 (1), CW1 (4), CL1 (2) = 23 points
I hope that helps & solves the mystery/confusion.
I suggest you demand your TV license fee back from the BBC for that unacceptable error!
