Its not like that , the decision of visa would be out online in same time as any other centre in India ,However all the passport travel to Delhi for stamping , so that takes time[but tat should not matter as your result would be online before you get your passport ] . In most cases , any decision would come in 20-30 days range. So I would suggest relax and go easy for the result. For me it was the most stressed 20 days of my life but once you get the visa in your hand your will be in 7th cloud .
All the Best.
