If you want to look at your all-in EV or red line for trivia sake because it's easily accessible, that's fine.

If you're interested in improving your game, I strongly advise you don't look @ all-in EV or red lines or at least don't let them affect how you play. Instead, review your sessions and play while you're playing and after you've played. A good poker player should understand why he wins when he wins and why he loses when he loses. If you don't understand, you need to be asking these questions WHILE you play and AFTER you play. This is why excessive multi-tabling is bad. The money is just jumping around. You can barely keep up with the action in front of you let alone take notes, reflect, and get reads.

The answers for getting better won't be found in all-in EV or red lines. After you get the money in, it was either done as a good play or a bad play despite whatever flop, turn, or river gets dealt. Whether you win your money @ showdown or not is also not important so as you're maximizing what you earn.
