100% Completion Help

[Tavrobel]

1. Did I lose percentage if I didn't get 650 points in Gunner Gauntlet? (the highest I get is 624)
2. Do I have to get all the GG and dressphere for 100%?
3. Is Via Infinito needed for 100%?
4. Where is the best place to catch chocobos?

1. Can I still calliberate the towers in Thunder Plains in Chapter 5?
2. Where is the best place to train, preferably the best place to receive AP and EXP other than Via Infinito?
3. I forgeot to oversoul all the monster in Kilika back in Chapter 1, how do I oversoul them? (I really need The End GG) <-- Umm, no you don't

1 - You don't lose %, but you don't get any %.
2 - No.
3 - You don't need Via Infinito, but it also means that you would have to do EVERYTHING ELSE TO THE VERY LAST DETAIL, plus Via Infinito to level 40 is a free 1.4%, the rest of it is another 1.2%. Also would require that you play the game through twice, which is already a big enough insult as it is.
4 - Anywhere with a Save Sphere, which means... anywhere. Except caves; try Kilika's woods, since the rate of getting Bold Chocobos is better (and therefore, better to send them out).

1 - Nope.
2 - Thunder Plains Cave, the machina are easy, just like the rest of the game.
3 - Kill a certain amount of the species type, and hope the next one that you see is oversouled. Save and Reset is a good option here. Otherwise, you'll have to New Game+ and start over, if the monster is CH. 1 only, OR try the Via Infinito. Another insult as the game is not worth playing in the first place, but be that as it may...

And the Mods will close if they wish. You don't have to ask them to do so "if necessary."

100% completion:
4. I mean the best place for the chocobo to appear (rate of appearing)?

Game completion:
3. I mean there are monster in Kilika Chapter 1, you can't go back in Chapter 2. In Chapter 3, new monster appear. how do I get to battle them back?

4 - Not a cave, not Zanarkand, not Bevelle, not Gagazet, not Macalania, not Mi'ihen. Anywhere else, the rate is the same (15%).
3 - Via Infinito, levels 1 - 15.
