Cyclone + Ruthless support - good idea?

Hey mates

Poe Wiki claims:
"With Cyclone, Ruthless Blows doesn't work as normal as intended, Ruthless Blow won't trigger every 3rd attack, however, it will trigger every 3rd series of spin attacks made by Cyclone."
So should I understand it as every 3rd full spin (which consists 2 hits) will be buffed?

Also,assuming it works as above does that make Ruthless a good support for Ignite/Bleed Cycloner,or should I consider something other than:
Cyclone + Faster Attacks + Melee Physical Damage + Added Fire Damage + Fortify + Ruthless ?

Thanks for tips and explanations,
have a nice evening mates.

If I understand it correctly, it doesn't apply to 2 hits, but to every third full spin (including change of directions, but only if this is due to pathing, not due to you moving your mouse).

It's overall a pretty strong multiplier, but a weird one.
I used it for a while, but swapped it for a more reliable, 100% uptime support.

Just test if you like it.
And of course, don't look at the tooltip, ruthless isn't factored into it.
