 Testing with Rytan's Reckless Renewal (singing skill). I have Singing Mastery maxed (

, Harmonized (9), and best singing item is Singing Resonance 26.
No focus/slope testing done with Doben's Spry Sonata. Which has songcap of 320 meaning 4.2 is the best focus I can obtain for the song. 80 + 90 + 260 = 430, capped to 420 / 100 = 4.2. Checking ${Me.Song[1].Mod} with MQ2 returns 4.2. So all checks out there
With Rytan's Reckless Renewal the song's mod returns 1.5. Possible way this is obtained.
80 + 90 + 260 = 430, cap to 420
420 - 120 = 300
300 * 0.5 = 150 = 1.5.
Doben's without the 260 from my gear I get 2.7 (80 + 90 + 100)
Rytan's without my gear I get 1.5 again, some how. So back to no idea
