That's an interesting site but needs to be read with caution.
Taking Leon Flint as an example the site appears to show him as No 1 in Berwick averages, when according to the official BSPL GSAs he's second in the team averages.
The team position has to be known to allow the correct team line-up and facilities to be determined. Why the actual average is concealed is more difficult to understand as it’s easy to calculate.
Fair comment but it's not just the physical setting up (which presumably would then remain in situ until a restaging), there's also satellite costs, broadcast time to fill etc.
