Nissan Skyline R33 Serial, Chassis , or VIN

I found these charts that they call the serial numbers, but they are the chassis number or equivalent of a VIN number. There were a few minor errors in the chart on Japanese Sport Cars, so I corrected them.  The R33 prototypes were first produced in 1992.  I find it strange that the R33 GT-R - BCNR33 starts with chassis number 000051 in 1994, but there is no listing for 1993. Although from the numbers there, 850 cars from 1994, so its not all pre-production.

I wonder if any of the other odd 3, 70,14,5 chassis produced in 1995 and 1996 give us any clue to N1's.

Some of these numbers don't exactly jive with what I have seen listed other places so if anyone knows how they counted them, let me know. 

Total Production 1995-1998: 
16250
        9871 Normal
        6551 Vspec (Including N1)

1995 : 8446
1996 : 4093
1997 : 2708
1998 : 1175
