Densify creating vertices at the wrong distance!

Hello! I am trying to create transects with points radiating out from a central point in all 4 cardinal directions. The points along the transects are at 1m, 20m, 40m, 60m, 80m, 100m, and then every 100m up to 2200m. I was doing it manually with Direction Distance tool, but it was taking quite a while (20 plots with 4 transects each). I tried to create lines using Direction Distance that went to 100m and 2200m and then to densify those (at 20m and 100m respectively), then to use Feature Vertices to Points to create the points along both transects.

The issue is that when I densify the 2200m transect (line) at 100m increments, it drops the vertices around 96m instead! I recreated the line a few times and did several tests to see if it changed but alas it did not. I didn't have a problem doing this for the 100m transects at the 20m marks. Worked like a charm. I tried densifying the 2200m transects at 20m as well but that also shaved off a bit and dropped the vertices around 17m.

What is going wrong?! Also, if you have a suggestion about how to better do this I am all ears. Till then it's back to the manual creation! Thank you.

So why would it be choosing to break it into the 96m segments instead of

100m since it is an even 2200m long?

if you look at my last pictoral example, I measured from he start point over 800 m which is 4 segment.  I created 10 points on the line and added the start and end point resulting in 11 segments 200 meters long  11*200 = 2200m
