The doubling point is the lowest possible winning percentage where it might be correct to double. Below the DP, it is always incorrect to cube, but just because you've reached the doubling point does not mean it is necessarily correct to double. It's different than the take point in that regard.
In order to have a correct double you must be above the DP but also have some market losers; if you still have a take next roll then there's no mileage in doubling. Here, black's take point is about 25% and you want to be closer to that before shipping it.
If you apply the Trice count you need to be about 11 pips ahead in the race to cube (I haven't adjusted for match score or wastage) and you only have a 7 pip lead.
As an exercise, calculate the doubling point for money play. Do you routinely cube when you reach that GWC?
