hm i dont feel natural that the document forging 2 need the athletic science pack, i see the purpose to include rabbascas own science pack, but here i would exculde it for a more natural / streamlined research

Also noticed that the athletic science pack has a great package size for rockets

If it was excluded, there would be no point in having the document forging 2 tech at all, since you could just research it immediately without building anything on rabbasca, and at that point having multiple versions of the hacking keys would be irrelevant.
Initial hacks are shorter for a bit more challenge, you solve the challenge by solving the planet and producing the science pack.

The science pack has a high package size since you need to move it out manually. This is mostly relevant with high science multipliers to reduce the manual jumps needed.
