And CDP1 (roughly what is assumed in BJA3, at least the part relevant to pair splitting) is also less optimal than, say, CDP (also evaluated at least by MGP's and my CAs), where the player can not only consider essentially *whether* he has split a given pair in modifying his strategy, but also *how many times*.
At any rate, for the purpose of this particular issue raised by dogman_1234, the distinction between CDZ- and CDP1 doesn't matter; the same assertion holds, namely, that the expected value of the two halves of the split are identical.
