GS to SS mech. Chain length

Hi,
My new bike came with a GS R8050 rear derailleur. I wanted short so I have bought the SS version. Fitted it tonight and as per chain length calcs, I removed an inch off the chain.
Now in a big rear big front combo, the chain seems so so tight. Now I can't recall if it was this tight before.
The chain was already 2 inches shorter than the calc suggests but it's a brand new bike so I thought the chain would be to spec.
Should I have removed an inch for GS to SS (medium to short cage)?
Oh and that's with a 28 cassette. The bike came with 30.

Always measure then cut. Generally around big/big, excluding the mech, plus a link.I don't do smileys.

The derailleur shouldn't have made any difference in the chain length. The measurement is big sprocket and big ring without going through the derailleur and add 2 links including the split link.I ride a bike. Doesn't make me green or a tree hugger. I drive a car too.0
