Could you please enlighten us little more about the Razakhani gat?

I have always maintained that Masitkhani gats have fixed bols, and are played in vilambit laya. But in recent times, there are several new compositions in vilambit laya with varying bols. Correctly these cannot be called as pure Masitkhani gats. On the other hand, it is noted that all Razakhani gats do not have a fixed bol pattern. In some compositions the gats, instead of starting from 7th matra, starts from 13th matra with the same bols. There are several other gats based on different bol patterns. But they are all still called as Razakhani gats. In my opinion, Razakhani gats were evolved on the basis of Bandish ki thumri. This concept however is now pushed into the background and gats are considered as vilambit or drut along with the name of the tala it is based on.
