I noticed the TOD arrow is usually quite conservative assuming correct winds have been insterted and no anti ice systems used. I usually wait to cross the TOD arrow and when it disappeared and FMA displayed “T/D reached” or “deccelerate” on the older version then only I initiate the descent. It goes immediately to idle thrust slightly faster than the target speed for a little while then usually settle again nicely to the target speed. I love those idle segments.

Good question and I’m not sure either. Would be cool if someone can bring some lights on this one. = )
