Acceleration multiplier is 1+2^(n-1) instead of 2^n

Using /tick command can show this clearly.

1. Run command /tick freeze
2. Use tiab to accelerate a furnace to x4, and put any item with furnace recipe into it
3. Run command /tick step 66, and the item isn't cooked completely
4. Run command /tick step 1, and the recipe is done

From above example we can see the furnace needs 67 ticks to cook an item with x4 acceleration, which is 3 times faster instead of 4 (which should be 50 ticks).

In addition, the actual acceleration multiplier for x8, x16, x32, x64, x128, x256 is x5, x9, x17, x33, x65, x129 correspondingly.

Oh no! Thanks for getting me this info. Ill have to see where the math went wrong. :(
