This has been off for a few years.

The database page lists these as the records used to calculate ranking
Braemar Stone       47' - 0.00"    ( 47.000000)
Open Stone            63' - 3.75"    ( 63.312500)
Heavy Weight         50' - 0.50"    ( 50.004167)
Light Weight          96' - 6.00"     ( 96.500000)
Heavy Hammer     132' - 2.75"   (132.219667)
Light Hammer       157' - 7.25"   (157.604167)
Heavy Sheaf           36' - 2.00"    ( 36.166667)
Weight for Height   19' - 1.00"    (  19.08333)

If we take the current database  #1 thrower, Daniel Tennison as an example:

Braemar Points:
Best throw 45'-4.50"  or 45.375  has earned him 978 pts in the database

However, 45.375/47 * 1000 =  965.4255319 rounded down to 965  pts

978 pts implies the record distance of 46' 4.75" 

45.375/(46 +4.75/12)=977.99 ==> the 978 points

----
Light Hammer Points
Best light hammer distance 124' 3" = 124+3/12 = 124.25
Points 124.25/(157.604167)*1000 = 788.365 points but database ranking gives 824 points

124.25/(150+9.5/12)*1000 = 823.95 points

---------------------

Backing out what appears to be the records used in the ranking calculations:

Braemar     uses 46' 4.75"  rather than 47'
Open         uses 63' 0.75" rather than 63' - 3.75"
HWFD        uses 49'10" rather than 50' - 0.50"
LWFD         uses 93' 8" rather than 96' - 6.00"
H Hammer   uses 124' 8 1/4" rather than 132' - 2.75"
L Hammer   uses 150' 9.5" rather than 157' - 7.25"
Sheaf seems correct
WOB           uses 20' 1" or just 20' rather than 19' - 1.00"



Am I missing something?

The weights for distance may be off because the records were set during this current season.
