4 pole mission resonance characteristics

I just finished my first shruthi build, a 4PM. It sounds amazing, but I have a question about the resonance in the different pole configurations. For some reason the resonance in the LP3 mode seems weaker than in either 2 or 4. I am prepared to believe that this might just be the nature of it, but I thought I would check if anyone else has seen anything similar. I just finished the build about an hour ago, so I havent had a chance to explore it fully.

Yes, this is normal.
