UP Alliance, the numbers

Now that SP and BSP have announced their pre-poll alliance for Lok Sabha 2019 election, let's look at the numbers. Let's look at constituencies where BJP won but SP + BPS got a larger vote share. So with this unlikely assumption that all the vote is transferrable, what would be the impact of these parties coming together. Following is the list of constituencies where SP + BSP scored more than BJP in the last election.
