I'll see what I can do to help.
You are right by saying a 100% increase is basically doubling the rate, and 50% isn't.
Ok, let me restart. Let's say you have 100% of something. It means you have all of that something, no more, no less. Like $1. You've got $1. However, if you were to add 100% to that, you would have 100% (your original $1) plus 100% = 200%. $1 x 200% = $2. If you add 50% to it, you'd then have 150%, or x 1.5. 1 x 1.5 = 1.5.
So, in terms of drillers, 1 factory can produce 18 drillers a day. You then add 50% to it, or multiply it by 1.5, equaling 27. 5.3h is the rate at which the factory needs to produce to get 27 drillers a day. Having a second tycoon adds another 50%, making your total now x2. 18 x 2 = 36, or drillers every 4h.
I know, it's a bit confusing. But it's how the game works, so just roll with it
