What a beautiful colour - but will i keep it?

I checked my FC account today, and to my great surprise the screen was a beautiful shade of gold.
Surprise, because by my calcs I needed my Y flight PVG-LHR at Christmas to gain the last point I needed to reach gold.
So when I checked the account I noticed what had happened:
I did a recent batch of flights on SQ, which should have netted me 20TP's however, only one of the 4 flights appeared on my account, so I went through the procedure to claim missing miles from partner airlines, and included ticket stubbs and boarding cards for the whole journey (4 flights). They appear to have credited all four flights I sent in, so I got double credit for one flight.
So now the question, for which I can guess the answer from all you honest V-Flyers.... Should I tell them? [}:)]
I guess the worst the can happen is in a few days, the mistake will be noticed and the offending extra flight deleted, resetting me to Silver and needing 1TP to reach gold.
And the best... they won't notice it, and I can show up at PVG before xmas, armed with a print out of my account details, use the Upper Class check-in and the lounge, and hey, who knows, maybe stand a better chance of any OP-Ups on offer.
I think I'll wait and see what happens. Does anyone else have any experience of similar problems when claiming partner miles?
