Attack Speed Discrepancies Between In-game and PoB

As I was min-maxing the attack speed on my cospri build I noticed discrepancy between the PoB attack rate and the in-game tooltip.

using https://pastebin.com/x9iiZG8W as build reference:

PoB says 6.44 attack rate, however in-game it says 6.45, slightly higher than PoB
If you add the 5% attack speed jewel Cataclysm Shrine into the empty socket PoB says 6.72 while in-game says 6.71, slightly lower this time
Finally if you turn on elusive for the 15% attack speed, PoB says 7.53, which is perfectly just under cospri's 7.57 breakpoints, however in-game it says 7.58, this time higher than PoB and also above the breakpoint.

Obviously it is 7.58 unless something is going horribly wrong with the in-game tooltip but bouncing back and forth between which one is higher is a bit puzzling.

まず、リンクされた Pastebin build にある 3 つの攻撃速度比較を再現します。base Cospri setup、Cataclysm Shrine jewel、Elusive's 15% attack speed です。PoB が使用している攻撃速度の計算を追跡し、その丸め処理または breakpoint の扱いをゲーム内 tooltip と比較します。不一致が説明され、表示される速度が修正または確認されれば完了です。
