How news weeks change my broker cost rankings

Broker cost rankings are not static -- news weeks scramble them.
In quiet mid-week London, one venue can look cheapest on my majors. In a CPI or NFP week, the ranking that matters is fill quality under stress, not the marketing spread screenshot from Tuesday.
What I re-rank on event weeks
I am not hunting perfection. I am deciding whether my usual ticket type (market vs limit) and size still make sense when the calendar is red.
How do you adjust cost comparisons when the week is packed with data -- different size, different venue, or simply fewer trades?

What I re-rank on event weeks
- Rejects in the +/-5 minutes around tier-1 prints
- Slippage distribution (not just the average)
- Whether I could flatten on the phone/app if the desktop platform hiccupped
- Symbol behaviour on XAU vs EUR -- they do not always degrade together
