Did you ever think about why industry standard strings have a zigzag for the saddles positions after setting intonation? Here are some saddles set up for industry standard strings:

The saddles for the 4th string (D3) is less sensitive to bending than the neighbouring strings, so the string length has to be made shorter as you bend the pitch less when forcing the strings onto the frets. This is true both for normal and equal tension strings from other manufacturers. Conversely, the 6th string ( E2) is more sensitivie to bending, so the the string length is longer as you sharpen the pitch more when forcing the strings onto the frets. There is a very good reason why the graph showing the sensitivity for conentional pitch bends matches this pattern as you can see in the following graph (see the zigzag in the G3, D3, A2 and E2 strings for the orange and yellow graphs of competitors’ strings):

The blue graph for sensitivity for Kemp Strings is flat for five strings because Kemp Strings have been mathematically optimised to give unprecidented equal response to player control. Now see how the intonation for Kemp Strings agrees with this, giving equal length for the G3 string downwards. Only Kemp Strings give equal sensitivity, or in other words, mathematically optimised repsonse to player control.
