Time Required to Cast Spells

Time Required to Cast Spells is on page 7 of 2e GURPS Magic in the section Principles of Magic.
Back then spells worked slightly differently: instead of going off at the END of the turn of when the last required Concentrate maneuver was spent, they used to go off at the START of the NEXT turn.
This made spellcasting a bit slower.
