1. that presumes that evasion does not come with a penalty to fire 
that makes it undesireable in some circumstances. Then you would have 
two modes. Dodge and Shoot.

Not necessarily so.

Okay, that assumes your firing solution, measured in ten-thousands of 
a minute of angle or degree such that it is tenous to begin with, is 
not badly disrupted by even a minimal manoevre. It may be.

Good point. 
Something to think of - lasers are lightspeed. Presumably so are 
sensors. Ergo any signal you get will be fractions to full seconds 
out of date. And then you beam has the same travel. So how far do you 
travel in seconds? Some distance. Therefore the manoevres may also 
have those seconds to take effect. Which may be enough to move your 
ship that km that makes the shot miss. I think there is a point.
