Where do the holes go on an F1 Skid Block

i've began designing my first F1 car to 2011 regs. I'm currently doing the floor of the car. In the regulations it states

'Beneath the surface formed by all parts lying on the reference plane, a rectangular skid block, with a
50mm radius (+/-2mm) on each front corner, must be fitted. This skid block may comprise no more than
three pieces, the forward one of which may not be any less than 1000mm in length, but must
:
g) have seven precisely placed holes the positions of which are detailed in Drawing 1. In order to
establish the conformity of the skid block after use, its thickness will only be measured in the four
50mm diameter holes and the two forward 80mm diameter holes ;
Four further 10mm diameter holes are permitted provided their sole purpose is to allow access to
the bolts which secure the Accident Data Recorder to the survival cell
'

Can anyone shed any light as to where these fixed 7 points are?
Thanks, Tozza Mazza

What do these holes actually do?

as it says in your highlighted text, at this positions the wear of the plank/skidblock is measured.

If you read the complete technical rules, you will find that there is a limit for the max. permitted wear of the skidblock during a race.

Some years ago Schumacher was excluded from the race in Spa (IIRC he won) because his plank/skidblock was worn out more then permitted by the rules.

ha course, that diagram is rather misleading, the holes are much smaller (5 cm diameter!) on a 30 cm plank.
