SNG's have such a low ceiling and are much harder to beat nowadays. Note: even years ago the ceiling they had was so much lower than cash games.
I'd completely rearrange and reorganize and have cash games be the focus. Here's some good reading:

And btw the # of games was inadequte.....at least when it comes to determining a winrate. When I played sng's 100 was 2 or 3 days. Now I play 4000+ hands of cash in a day. Nobody in STFF will start taking your results seriously until 500 sng's and 1000 is so much better but still not really that large a sample.
Edit: Oh just like to say...if you're still gonna have him play sng's which I think is silly have him read the STTF here, have him learn ICM, and have him get sng power tools or a similar program.
P.S.
Btw how can one be a good monopoly player?
