So i redid the test with a better rda. The one i used before had hollow posts which maybe gave some bad results. Today i took the in'sane which is a lot easier and gives more accurate results. Measured using the coilmaster v2 with kanthal 28 awg without burning.
I'm doing this just because most of the times we take things for granted without testing.
Here are the results

The coil of the 5 wrap 1.21 and 6 wrap 1.45 were at the same position, just above the air hole meaning that the excess wire after the screws was less for the 1.45 coil or the length of the wire between the post was longer with 6 wraps. Hope this is clear.
