well let me try to explain, knowing plarium their math is always upside down so it will go like this

Regular exchange for 500 denari is 60 min.

40% in their case means you get 40% more in the same time so it means

500+40% = 700 denarii per 1 hours, which lead us to 42 min for 500 denari

hope this helps

Hoi Tripl,

Thanks for the expanation and yes it is helpfull.I was thinking that direction but did not figure it out yet.

It is the same when big company (electronics giants) says you can buy tax free on a certain date  with 21% tax 100€ + 21% is 121€.

if you think 121€ - 21%= 96 so it is the same error in backward calculation.

But for me it was not clear the 40% boost was on the amount of Dinarii instead of 40% boost on time.

Thanks again regards,

Jos

Hi! It's not a bug. The boost increases speed of conversion, it doesn't cut the time. Which is a different formula.
