Any interest in an IS-WAS for SH3?

Awesome work Hitman.

The only downside that I can see is that you are going to need the target to shift at least 6 degrees of bearing between range marks (a problem with any rule that doesn't have an ST scale).

The current rule I am using (A pocket sized Pickett N200-ES Trig) has both an S and an ST scale. I had to use the ST scale yesterday on a slow moving target, because the angle they had moved between my range marks was 5 degrees. I didn't need it to find the AOB, but distance target travelled. I was using 100 second intervals for my marks so that I could skip the meters travelled/seconds calculation. It just made the math easier.

For the AOB calculation you'd only need an ST scale if the target was coming pretty much directly at you or directly away from you.

Still, the US version didn't have an ST scale, so I wouldn't include it.

We just have to be aware that apparent target motion will have to equal at least 6 degrees to get a target distance 'distance travelled', so that we can calculate speed.
