[QUOTE="Gruns, post: 4536431, member: 10312"] [b]Formula revealed!!![/b] So I took my TI-83 and plugged in some numbers to form a function converting old CR values with new monster levels... Here's the quadratic formula: y=.0362x^2+.4932x+4.301 (Where x is the original module level and y is the level as it applies to 4E) A quick glance at the formula will tell you right away that even an older level 1 module now equates to nothing less than around level 4.8304 in 4E. The r^2 value is .9246, which is lot cleaner than I expected. When graphed, the function shows a slight increase in slope as the original module level increases. This was expected as the cap increased from level 20 to 30. You're probably wondering why I went with a quadratic formula over a linear regression: The linear regression had an r^2 value of just .6152 which of course makes it nearly useless as far as accuracy goes. In fact, the linear regression formula of y=5.3497+4.2658*[I]Ln[/I]X means that the lowest starting value a 4E adventure could have is level 5.3497, assuming there are no older modules with starting level values less than 1st. (And logically there wouldn't be as characters can't start below 1st level). Glad I could help. Gruns [/QUOTE]
