Hit Rate with Max Unleash Seals is incorrect when Cast Rate is high enough

What is the value from the calculation in-game?

In-game when waiting for Max Unleash Seals, I believe Hit Rate should be calculated as the lower of the following two:

1. 1 / Time to Gain Max Seals
2. Cast Rate / (1 + Max Seals * 0.1)

So the value would be (with placeholder stats):

• Time to Gain Max Seals = 1.5s
• Cast Rate = 3/s
• Max Seals = 8
• 1 / Time to Gain Max Seals = 1 / 1.5 = 0.67 Hit Rate
• Cast Rate / (1 + Max Seals * 0.1) = 3 / (1 + 8 * 0.1) = 1.67 Hit Rate
• 0.67 is the lower of the two, so that should be the Hit Rate used

What is the value from the calculation in Path of Building?

In PoB, when config is set to Wait for Max Unleash Seals, PoB calculates Hit Rate as whichever is lower:

1. 1 / Time to Gain Max Seals
2. 1 / (Cast Rate * 1.1)

So it calculates the incorrect value (with placeholder stats):

• Time to Gain Max Seals = 1.5s
• Cast Rate = 3/s
• Max Seals = 8
• 1 / Time to Gain Max Seals = 1 / 1.5 = 0.67 Hit Rate
• 1 / (Cast Rate * 1.1) = 1 / (3 * 1.1) = 0.30 Hit Rate
• 0.30 is the lower of the two, so it chooses that (and so higher cast speed = lower hit rate and DPS currently)

How to reproduce the issue

1. Select Arc as the main skill
2. Add Unleash Support to Arc
3. Tick on Do you wait for Max Unleash Seals?
4. Increase cast speed until (Cast Rate * 1.1) > Time to Gain Max Seals (On new file, 100% increased cast speed is enough)
5. See incorrect Hit Rate based on inverse of 110% of Case Rate

Reproduce the issue with the linked PoE1 build code using Arc, Unleash Support, and “Do you wait for Max Unleash Seals?”. Trace the hit-rate calculation for that setting, then verify it uses the lower of the seal-gain rate and the cast-rate expression involving Max Seals; confirm the result at high cast speed.
