we have reached our 10k replays per month quota in 20 days, by using a 100% error sampling rate
we would need a sampling rate < 0.64% to stay under the quota
from now on, we will be using a 50% error sampling rate to have a bit of margin, and have a rounder number that is easier to reason about (1 out of 2 error sessions are recorded in Sentry)
