Weird Comp Structure

Got an offer for an AM position where commissions are only paid out once you hit 90% of Net Retention Revenue quota. That seems very strange to me. In my experience, payout has been tiered % wise as you chip away at quota (3% when 0-60% of goal, 6% when 61-90% of quota, etc)

The role is also a paycut because it’s a research company, but their whole teams hit quota so OTE is more realistic than tech.

Has anyone seen a commission structure like this for an AM position? I tried to negotiate higher base/a signing bonus but there didn’t seem to be flexibility. Appreciate anyone’s insight in advance.
