                            Please, keep in mind that when using gems to train troops, adjusting the amount of troops to train to use exactly 3 day and 1 day speed-ups, is more cost effective than using several 15, 8 or 3 hours speed-ups. This might require Barracks Capacity of at least 13,000 troops to train T2 units using 1D speed-ups.
