Examples then go on to match u sub 1 to the first strata (u sub 4i+1) and u sub 2 to the second strata (u sub 4i+2), so I assume the index i is always zero. I must be missing something here, what am I not understanding?

For example, if we had ten strata, would the notation then be u sub 10i+1, u sub 10i+2 ... u sub 10i+10?
