How much difference in the ORS is there with 4bar & 5bar Flight Attendant?

I am currently configuring my cabin for my new CJR900 NewGen. If I have 9 business seats I will have a 4bar for Flight attendant, where as if I have 8 Business seats I will have 5bar for attendant. My question is, how many points difference is it on the ORS for 4bar and 5bar attendant. I currently have ORS 88 for Business with my CJR1000 NewGen (5bar Flight Attendant) but my next competitor has 82 ORS so clearly it would be beneficial to have 9 seats instead of 8 but to what detriment?

 

Flight attendants have only indirect effect on ORS rating. FA affect image, which in turns has effect on ORS.

So if 5bar scores me 88 ORS, What do you think I would score on the ORS with 4bar for flight attendant?

Initially, same. Please reread what I wrote.

Okay thank you I just wasn't sure exactly how detrimental it would be.
