Yes, indeed, turns out BI just cherry-picked the worst part.
When allocated 100% to cash (vs. vacation) oncall pay amounts to more than an extra full paycheck every quarter.
If you don't notice an extra $10,000/year post-tax then please, send some of your moneybags to someone who appreciates the value of a dollar. Like me.
For me it's (off the top of my head) about 10%. Definitely noticeable.
