Count the hachis (hachi roku day at Fuji Speedway)

This video shows what the average hachi roku enthusiast will drool over: 4:25 minutes non-stop hachi action on hachi-roku-day at Fuji Speedway!

Anyone actually able to count them all? I lost track at a certain moment and my guess is somewhere near 30!
