The clarification is very much comolictaed...It might have been read what he said excellent in case you could have created it a tad simpler.
The advantage of pairing is greatest on tasks which the programmers never absolutely understand prior to they start: that's, challenging tasks that decision for creativity and sophistication, and for novices compared to industry experts.
