Which Solid Fuel recipe to use

On 05:05, 19 June 2016‎, Hamburger changed the adjusted ratio (Heavy Oil to Solid Fuel) from 2:1,5 to 1,3:1.

"Heavy Oil has a much worse ratio (2:1) and should be cracked into Light Oil first instead. The cracking process changes the ratio for Heavy Oil to 1.3:1, which is much better."

I think the old ratio of 1,5 : 1 was correct. Let me recap this in short:

2 Heavy Oil : 1 Solid Fuel
-> 2 Heavy Oil : 1,5 Light Oil
-> 1,5 Light Oil : 1,5 Solid Fuel
-> = 2 Heavy Oil : 1,5 Solid Fuel

Correct me if I miscalculated. Otherwise, I will change the Page in few days.

That is not so much a miscalculation as a miscomparison. Here's an alternate breakdown:

2 Heavy Oil : 1 Solid Fuel
OR
2 Heavy Oil : 1.5 Light Oil
-> 1.5 Light Oil : 1.5 Solid Fuel
-> 2.0 Heavy Oil : 1.5 Solid Fuel
= 4.0 Heavy Oil : 3.0 Solid Fuel
= 1.3 Heavy Oil : 1.0 Solid Fuel

You must use the ratio of Heavy Oil to one Solid Fuel, which is either (2:1) or (1.3:1).

The 1.3 is 1.3333333, obviously, one and a third. It rounds to 1.3.

To get (1.5:1) it looks like you are leaving the (1.3:1) expressed as (2:1.5), and then comparing the 1.5 Solid Fuel from one ratio to 1 Solid Fuel from the other ratio. But that doesn't make sense, you can't ratio Solid Fuel to Solid Fuel.
