As you wish Brianh

some things are stunningly non-obvious when it comes time to optimize 
REBOL


>> a: 1x1 b: 10x10 s: now/precise loop 1000000 [second b - a] difference 
now/precise s
== 0:00:00.5


>> a: 1x1 b: 10x10 s: now/precise loop 1000000 [b/y - a/y] difference 
now/precise s
== 0:00:00.969

so, pair refinements are slow?

all path access is slow...but I woudn't have thought that using a 
series function and multiplying both values in the pair would be 
twice as fast!

in my mind it would have been roughly equivalent.

that's very interesting for DRAW blocks. I wonder if R3 has the same 
issue.

just tried it... A100

in R3 they *are* roughly equivalent  :-)

in fact in R3 the second version is ~ 10% FASTER  !

so, claims that the path access is faster in R3 seems to be true 
across the board

btw the first version is exaclty the same speed as in R2, on my system.

I don't use first, second, third .... anymore in R3.

when I have the choice, indeed

yeah, its much easier to read.  I only use first/second in R2 because 
their faster.
