The article says:
1.9% at 12
which is for 3253824 objects (I get 1.86%).
However, that was three years ago, and we now have over five million objects,
so the collision possibility is 4.5% now.
If we add another 2 million over the next three years, then the probability
will be over 8% then.
I've attached my spreadsheet for you to have a look at.

Fix checkpatch. This is an entirely reasonable supposition.
