Dear Martin,

Sorry to reply you late.

You are talking about 90% 2-sided confident interviles based on
percentiles. I don't think it is same as coverage interval.
Confidence and Coverage intervals are conceptually different.
Confidence interval is about population parameter, whereas coverage
interval is about the individual sample values.
