a somewhat pointless technical question regarding Neversummer boards

I have last year's SL...no issues with the board, but i was wondering how board companies determine a specific board sizing's sidecut radius...It does not seem to be at all a linear nor predictable, at least when It comes to this company's boards.

So why is the 151's sidecut so shallow compared to the next size up?

I'm guessing it's something to do with the maths. I'd suspect the graph that determines the sidecut-length relationship to dictate the desires amount of flex/stability/pop/etc is not linear and just happens to dip that low for that particular size.

My guess would be that in that size, they drop the use of the longest vario sidecut and possibly pick up a tighter geometry near the nose. The "average" might show a seemingly substantial jump, compared to what is used in the other models.

if you calculate sidecut depth as 1/2 the difference between waist width and tip tail width, you obtain the following values:
151 2.1
153 2.2
155 2.2
158 2.25
161 2.3
164 2.4
those numbers appear to follow a pretty natural progression to me. Perhaps I've missed the point of the question though. As a board builder, I can tell you, it's also quite common to round numbers off for marketing material. The specs listed only indicate 1 decimal place. 28.5 could in reality be anything from 28.45 to 28.54. Consider the same thing for the waist width and your depth values could be off by almost .05cm
