One of the opportunuties to excel provided by developemnt of web sites is the lack of a hardware standard to code to. This forces you to reduce the minimum system requirements to some worst case that is a less than optimal configuration so the majority of your users can access your site with a reasonable degree of functionality. In this case my site is designed to be used at 800x600 resolution or better. This constraint limits the amount of data I can display on the screen at one time. While not the optimum for those with high resolution monitors, the tab configuration provides a workable solution. This limited display space limits the functionality that is practical in internet applications like this one. If it were an intranet application or a windows forms application much additional fuctionality could readily be added.
If you could suggest a alternate organization of the data items to be more usable within those constraints I'd certainly welcome your thoughts.
I'm not sure that you and I are talking about the same adjustments for elevations. To aid in our discussion I created a sample page with two trajectory charts the top one for a normal zero, the bottom one showning the trajectory @ 10000 ft with the original zero:
You will note the point of impact @ 500 yds has changed from -36 in to -30.7. This is the effect I've been referring to. Is this what you've been talking about?
As far as BC calculations go, I think that should be on a separate page rather than trying to add even more to the existing page.
I've been giving the graphics idea some thought and I think that is doable with a little more thought, though I will probably not limit you to 3 at a time.
I definitely have no desire to attack internal ballistics at all, way beyond my knowledge and comfort level. I don't think anybody will sue me over a bad trajectory calculation, the same probably wouldn't hold true with a mangled rifle or worse.
I think the adding the mils display woud be pretty straight forward, probably need to change the method of selection but doable.
As far as the database type addons go, I'm not to sure where to go with those.
