There's literally no reason with award dates is there...even when you're trying to estimate when you should know, you can't as there's people still waiting for middle of Feb but then beginning and end of March decisions being made 🙃
My scan dates 02/04 so just gone 9 weeks and had 2 letters, and probably another 10 weeks or so bu the looks of it which i dont mind, i wonder if it goes by area/where your forms are sent for decision maker 🤔
