Galaxy ship design aid From: amead@s.psych.uiuc.edu (Alan D Mead) Date: Mon, 28 Jun 1993 21:28:52 +0000 I believe the below chart is correct, but my purpose for posting it here is to verify that. As a quick check, the numbers seem reciprocal. Eg, the Pkill for 3.00 is one minus the Pkill for 0.33 (to within rounding error). This is corrcet, right? One inference I draw from the below chart (and a bit of high school math) is that a slight difference in tech levels can render your cloud of [1 1 1 1 0] escorts impervious to attacks of size 1; the Pkill for two such drones attacking each other with equal techs (ratio = 0.464) is 0.22. Have fun. Please advise me if the chart is in error. -alan mead ------- Galaxy v3.32 Probablity of a kill for a given attack/defense ratio. .00 .01 .02 .03 .04 .05 .06 .07 .08 .09 0.2x 0.000 0.000 0.000 0.000 0.000 0.000 0.014 0.028 0.041 0.054 0.3x 0.066 0.078 0.089 0.100 0.111 0.121 0.132 0.141 0.151 0.160 0.4x 0.170 0.178 0.187 0.196 0.204 0.212 0.220 0.228 0.235 0.243 0.5x 0.250 0.257 0.264 0.271 0.278 0.284 0.291 0.297 0.304 0.310 0.6x 0.316 0.322 0.328 0.333 0.339 0.345 0.350 0.356 0.361 0.366 0.7x 0.371 0.376 0.382 0.386 0.391 0.396 0.401 0.406 0.410 0.415 0.8x 0.420 0.424 0.428 0.433 0.437 0.441 0.446 0.450 0.454 0.458 0.9x 0.462 0.466 0.470 0.474 0.478 0.481 0.485 0.489 0.493 0.496 1.0x 0.500 0.504 0.507 0.511 0.514 0.518 0.521 0.524 0.528 0.531 1.1x 0.534 0.538 0.541 0.544 0.547 0.550 0.554 0.557 0.560 0.563 1.2x 0.566 0.569 0.572 0.575 0.578 0.580 0.583 0.586 0.589 0.592 1.3x 0.595 0.597 0.600 0.603 0.606 0.608 0.611 0.614 0.616 0.619 1.4x 0.621 0.624 0.626 0.629 0.632 0.634 0.636 0.639 0.641 0.644 1.5x 0.646 0.649 0.651 0.653 0.656 0.658 0.660 0.663 0.665 0.667 1.6x 0.670 0.672 0.674 0.676 0.678 0.681 0.683 0.685 0.687 0.689 1.7x 0.691 0.693 0.696 0.698 0.700 0.702 0.704 0.706 0.708 0.710 1.8x 0.712 0.714 0.716 0.718 0.720 0.722 0.724 0.726 0.728 0.730 1.9x 0.731 0.733 0.735 0.737 0.739 0.741 0.743 0.745 0.746 0.748 2.0x 0.750 0.752 0.754 0.755 0.757 0.759 0.761 0.762 0.764 0.766 2.1x 0.768 0.769 0.771 0.773 0.774 0.776 0.778 0.779 0.781 0.783 2.2x 0.784 0.786 0.788 0.789 0.791 0.792 0.794 0.796 0.797 0.799 2.3x 0.800 0.802 0.804 0.805 0.807 0.808 0.810 0.811 0.813 0.814 2.4x 0.816 0.817 0.819 0.820 0.822 0.823 0.825 0.826 0.828 0.829 2.5x 0.830 0.832 0.833 0.835 0.836 0.838 0.839 0.840 0.842 0.843 2.6x 0.845 0.846 0.847 0.849 0.850 0.851 0.853 0.854 0.856 0.857 2.7x 0.858 0.860 0.861 0.862 0.864 0.865 0.866 0.867 0.869 0.870 2.8x 0.871 0.873 0.874 0.875 0.876 0.878 0.879 0.880 0.882 0.883 2.9x 0.884 0.885 0.886 0.888 0.889 0.890 0.891 0.893 0.894 0.895 3.0x 0.896 0.897 0.899 0.900 0.901 0.902 0.903 0.905 0.906 0.907 3.1x 0.908 0.909 0.910 0.912 0.913 0.914 0.915 0.916 0.917 0.918 3.2x 0.920 0.921 0.922 0.923 0.924 0.925 0.926 0.927 0.928 0.930 3.3x 0.931 0.932 0.933 0.934 0.935 0.936 0.937 0.938 0.939 0.940 3.4x 0.941 0.942 0.943 0.945 0.946 0.947 0.948 0.949 0.950 0.951 3.5x 0.952 0.953 0.954 0.955 0.956 0.957 0.958 0.959 0.960 0.961 3.6x 0.962 0.963 0.964 0.965 0.966 0.967 0.968 0.969 0.970 0.971 3.7x 0.972 0.973 0.974 0.975 0.976 0.977 0.978 0.979 0.980 0.981 3.8x 0.981 0.982 0.983 0.984 0.985 0.986 0.987 0.988 0.989 0.990 3.9x 0.991 0.992 0.993 0.994 0.995 0.995 0.996 0.997 0.998 0.999 4.0x 1.000 1.000 1.000 1.000 1.000 1.000 1.000 1.000 1.000 1.000 Rows are the units and tenths and columns are the hundreths.
