''...Not correct...''
Yes TOGA can you use whenever you want if you so want too.
Often it has too do with limitations,hot weather,high weight (You can FLEX
at MTOW if runway is longer than ''lowest runway required at MTOW'').
So yes, my previous reply wasn't totally correct but then there still are one question.
Why would you use TOGA when you are NOT limited?...
''On runways less than 2500 m need to use CONF 3 tables
Charts based on air conditioning OFF''
PS. He means that under 2500 m you need to use CONF 3 tables. Thoose
numbers is not at MTOW, but shows the MTOW from a specific runway.
