is it so khaderbhai? We are not ordered to follow our Imam itself. But we are asked to follow the Quran and sunnah and the teachings of sahaba e kiram, the people who learned Islam from its very source. I have read in many books that Haz.Umar (r) performed taraweeh in 20 rakaaths. So i think its is the right way. Umar (r) w'll not do anything against the teachings of prophet. I dont think most of our mutawas are performing prayers in right way, as i know many mutawas , even they are learned , they are not aware of how the prayer is performed.
