Hi!! I have found a very big difference simulating a battle between 10 Death Stars and several thousands ships and defenses, when using Speedsim results in 0.3-0.7 Death Stars remaining, but when using Dragosim none of the Stars are destroyed (10-9.99 remaining)

. I discovered that when clicking in the case named "Use Old Shield Calculation", the results of both simulators were the same, none of the stars destroyed.
The version of Speedsim I'm using is SpeedSim.exe v0.9.4.2b, which one is correct Dragosim or this one? What is the cause of such a huge difference?
Thanks in advance 4 your help!
