You do not qualify since you are short of the required days of physical presence. If those number of days is always consistent within the 4year timeframe for your application, then you do not always have a chance. You might have a chance if the new requirement (1460days of 6 years) comes into effect, since the timeframe taken into account is longer(6year window). If we'll consider your figure(average of 1000 days in 4years), that's 250days in a year. You'll end up having 1500 days in 6years. That if your practice of staying in remains consistent in a year.
