We're mixing things and it shouldn't be so.
The 2011 Paris result doesn't count for London because it's 2011, not 2012. So that is why it won't count this year at all in the Race To London. The 2012 result will enter the Race to London rankings, whilst the 2011 result will be ignored.
Well, in the rulebook the qualifying for the WTF is nomore based on the "Race to London" but on the ATP rankings (which is why the ATP had stopped displaying a Race on its website for two years) :

c) Players positioned eight (8) and below in the South African Airways ATP Rankings as of that Monday.
The "Race to London" which is displayed by the ATP on its website now is only a help for people because it's easier to follow the way to the ATP rankings on the monday after Paris tournament which will actually determine the qualifying to the WTF.
Which means that on monday after Bercy, the ATP rankings and the "Race to London" should coincide because the former determines the official qualifying to the WTF, the latter was a help to "predict" that qualifying.
It only says the number of optionals is adjusted when there are not 12 mandatories, not if more than 12 mandatories are accepted.
yes, "when there are not" doesn't mean "less than", it means when it's different. The evidence of that is that it's "adjusted accordingly", not "increased by one" as they say in previous sentence for the case of players who are not allowed to enter mandatory tournaments as direct acceptances.
