I think this response strongly supports the fact that you aren't really dictated to by the SI at all. If the same hole was SI 16 you would play it the same - it's the strategy that represents your best opportunity of making a point with a realistic chance of 2 and a significantly reduced chance of 0. A more aggressive strategy won't increase the number of points over time but brings that sin of all sins in medal play into play - the nett triple bogey!
Surely it does matter if in a matchplay scenario I am giving my opponent a shot? Though saying that that does suggest to me that it is not because of the SI per se - more that I am giving a shot. In my stroke play you are quite correct.
