In Bloons TD 5, the Monkey Ace drops Pineapples every other time it shoots darts. In Bloons TD 4, the Monkey Ace drops Pineapples every time it shoots darts. If you upgrade your Monkey Ace to Operation: Dart Storm, the Pineapples will get dropped quicker because the Monkey Ace shoots quicker. However, buying the opposite tier-3 upgrade, Neva-Miss Targeting, it will deploy pineapples at the normal expected speed.
