Hey,
It shouldn't be an issue of negative impact in any case. They will rely on your file for such decisions, that is negative or positive.
But I would advice against it. Its been around 9 days since you applied but CHD CHC takes about 7-10 days in October itself, so expect around 15-20 now. When I joined I went through all old posts to check how much time does it take for people to receive their VISA and I can say for most of the people applying in November it was 18-20 days (holidays included). People who applied on 20th November or even after that that is 25th got it in about 20 days, I remember 3 friends applying together on 18th November and getting their VISA on 6th December. But then there were a few isolated cases where people were waiting even after 20 days.
