Dear colleague (I'm a physicist too),
"""""""i do not understand your rationale behind the formula used to calculate the POI?"""""""
I send you a new version of my file and the explanation.
I tried the formula =BfX_Zx() (see comments at cell H4) but I couldn't use inclination.
When the inclination is zero I have the same results with your BfX_Zx() formula.
Can I use another BfX formula in order to have a result with an inclination ?
"""""""did you know that bfx is able to convert most of its outputs, e.g. =bfx_d("cm";.... and bfx_d("moa";.."""""""
I discovered it later :-) Very usefull !!!
"""""""When I was involved with Fieldtarget, I found it quite hard to compare measured velocity data of HN FTT pellets with the values of chairgun (BfX did not exist then). What is the situation now?"""""""
I'm not sure I understand your question. Can you be more detailed ? you have measured velocity data of HN FTT pellets in different distances and you wanted to compare your values with chairgun ?
Some more to tell/ask you ..
1. as you can see I use a custom drag table which I took it from chairgun (GA profile) (black background cells).
if pressure, temperature or humidity change are these values change or remain the same ? (logically they change) ...
... so in which temp, humid, press conditions must these values be measured, in order BfX make right calculations ?
ps
later on, I changed some of these values with the red ones, right next to them, in order to have the same results between chairgun and BfX. I used solver for this.
2. in your help file you wrote "Cd=BfX_Cd(v0; df=GP)".
I think it would be more user friendly if you write "Cd=BfX_Cd(v; df=GP)" because Cd change with velocity, and vo is just the muzzle velocity.
Thank you for your project !!!
