Andy,

"instructions per second" and "user source code lines per second" are
two different things and cannot be compared. Its the old Apples and
Oranges thing.

"instructions per second" relate to the number of instructions the
processor can handle each second.

"user source code lines per second" relate to an average based on
coding style.

For instance:

a=1

compiles into 3 instructions.

a=abs((a*2+9)/2)

compiles into 12 instructions.

If (a=1) then a=abs((a*2+9)/2)

compiles into 20 instructions.

The details of how fast the 8-bit ooPIC interpreter chips operate can
be found on the following page which does a comparison to the Basic
Stamp which also publishes speed in "Instructions per second":
