Item Mechanic Changes?

[Mario & Sonic Guy]

Lately I've been wondering if the mechanics for certain items have been modified. During my times studying the mechanics for the size changing items and Metal Box, I have been able to get down the following information...

Default Size Mechanics
s = size multiplier
r = ratio factors (launch rate, crouch cancel, smash attack charge, rage, stale-move negation, etc.)

• Damage Dealt: ((s - 1) * 0.8) + 1
• Weight: ((s - 1) * 0.6) + 1
• Knockback Taken: r / (((s - 1) * 0.5) + 1)

Lightning Size Mechanics

• Damage Dealt: ((s - 1) * 0.6) + 1
• Weight: ((s - 1) * 0.6) + 1
• Knockback Taken: r / (((s - 1) * 0.5) + 1)

Metal Box

• Weight Multiplier: 4.5x
• Knockback Resistance: 30 units

Now, I don't know if Smash Ultimate will reuse the same formulas for the size changing items and Metal Box as in Brawl and Smash 3DS / Wii U, but with the game's release coming soon, I thought it was worth analyzing.
