Tracing Monero via fee structure

Chainalysis uses the fee structure to analyze monero transactions. I thought using the fees hardcoded into monero-gui should be fine, but x0.2 does not show up at all, x200 is less used than x100 (even though not available in the gui, but x200 is).

I guess these fee multipliers are used by other wallets a lot.

Is x1 the safest to use? Is the gitter in between caused by "automatic" transaction priority? Would it increase privacy to sync fee structures between different clients?
