The reduce mins for restricted ATP's are 1,250hrs for approved two year degrees, 1,000hrs for approved four year degrees and 750hrs for military pilots.
For the 1,250/1,000hrs mins, all ground and flight training must be done in accordance to the 141 syllabus.
What is nice though is if you have 1,500hrs and are of age, you can apply for a RATP with only 200hrs XC instead of the 500hrs normally needed as long as you meet every other flight requirement in 61.160. Once you reach 500hrs of XC, then your license will become a standard ATP.
