Top Lefthand one is Push2Pass amount left in percentage. Bottom Righthand 4 numbers are tire pressures in bar.
Ok the tyre pressure one makes sense, the other one top left middle is a percentage? because its different all the time and alters without using p2p, which on a side note p2p doesnt seem to work, or is it just me?
Delta means projected laps of fuel left at the end of the race at current fuel consumption. P2P only works after the 1st race lap so make sure you test it after that.
Oh the middle one, i thought you meant the P2P one, apologies. Yeah the middle one is the fuel delta like Oez mentioned. P2P activation is only permitted in race session (and it indeed activates in lap 2 like mentioned.)
