I promised an update regarding re using the marinade and putting chicken straight in without the 15 min in lemon juice etc first.
Not much difference at all. The is a but and that is I thought the 2 nd batch was very slightly less tender / moist. Over rider is also that I know that it had an extra 30 seconds under the heat which may account for this.
Verdict - next time les marinade for same meat or I will do more meat in Mick's marinade measures and do this meat the lemon juice first.
Wife not impressed as she put on 2 lbs since Friday .

. Passed the taste test though. Placated her with some pressies to wrap and some Sellotape.
