Scale counting questions determining bci vs bcc

[ChristinaM]

If I did this right, I counted 257 ventral scales on my bci's shed.



to be sure I am using the correct terms, by ventral scales, I counted the larger scales on the underside ( belly ), from where they start past the head, down to the vent ( on the shed you can see where his spur's are, this is where I stopped ).

Here's a pic of where I started, and where I finished:





My questions:

1. Did I count right? ( meaning where I started and finished)
2. If I'm reading the chart right and understanding it ( http://home.att.net/~crinaustin/BoaGeneral.htm#Table2 )

just this scale count alone would prove him as BCI.....yes?

or do I need to do more counting?

If I need more counts, if I post pics can someone point to starts and finishes for other scale counts?

thanks.
