Vivek Express: ऊंचे नीचे रास्ते और मंज़िल तेरी दूर.

I checked fare from NZM to KYN for 11 & 12 April. For 11 number of seats available is 305 and fare showing is Rs.2,710/-12 number of seats available is 285 and fare showing is Rs.2,525/-. Not able to understand, I know this train is under dynamic fare, but how is higher fare for more number of seats? can any one pls help me to understand the logic?
