There's actually 2 battles with Leon - one's the A3, and one is post IE. The post IE needs to be beaten at least once to unlock Acceleration. It's also the hardest single event in the game to my knowledge, but it's also a one round all in, making it arguably easier than an IE.
The first note about the IE is that you ideally want to move at least 5 idols to higher ranks first (Since you can make an A1, you can always just yank up other idols to A3 or higher). The sheer number of SP you get for ranking up should even the odds, and you want to bring in two fresh idols after winning the intermission. As priority, you want to make sure your non leads has all the passive boost skills (namely, increased voltage per note, and better appeal voltage/counter voltage) as all the skills stack on the unit.
If you're having trouble, bring your best team and your best song first, and try to force appeals out of the opponent. They regenerate somewhat, but it is possible to force them to deplete somewhat.
If you're desperate, and you think you can pull it off, lose the first round, then go for a best of three, and have your best two backups with full appeals available and force the last round to be one where you should have the appeal advantage. (And win round 2)
From my knowledge the highest memory total an individual idol can have is 5, but I've never taken anyone past 4.
I've managed appeal totals of 16+ (Quintet) although I imagine 15 is the cap for a trio.
Second note is that if you're still 4 idols out from complete, you may not have access to the tier 3 lessons. You'd ideally want all of those stacked on your group prior to IE if you're having trouble.
Last but not least is that you can always level up. Each level will add primary stats (DA, VI, VO) to an idol, and they never hurt.
The multipliers affect the fan and the money gain from using a song. I don't think it affects your score though.
Appreciate everyone's help. Wouldn't have gone far without you people.
1. Got to Rank A1 with my leader. (the other two are in B3). I can destroy any A1 festival battles since I've got 10 memory, triple memory appeal skill, and learned all unique skills with my leader. I managed to beat Leon's battle. However, the IE totally crushed me completely.
No matter what skills I learned, it's still the same result. IE rival can score really high, has burst counter, and has Touma's burst which will totally wipe out your voltage (so no point in trying to burst counter). Only song I can win against is with Tonari Ni.
Is there any advice? Otherwise, I'll just do some level/rank grinding and learn more skills since I still need to unlock 4 other season songs.
2. What does the song status indicate? (example Fresh = 1.5 or Keep = 1.3, etc).
3. Is there a maximum amount of memory for each idol or total as a group?
FYI- I'm helping my brother with this game. He might post some questions here if I don't know the answer.
