AFAIK this is the equivalent of overexposing by 1/5 f-stop. I have also read that I can under/over expose a color negative film by 1 f-stop without any major problems, the lab will correct this during the development process. So Reala is a color negative film, and an overexposure by 1/5 f-stop would likely be "corrected" by the lab.
A couple things. First rating at 80 is a bit over 1/3 not 1/5 of a stop. Second, color neg film has less tolerance for underexposure then overexposure, and low contrast negative films often will give you muddy shadow detail. Hence the trick of rating the film at a lower ISO or using a + EV. Old Kodak Vericolor was the worst for that. It was an ISO 160 film that everybody rated lower. The most common was 100 though 125 and even 80 were not uncommon. My guess is that rating Reala at 80 will give you better shadow detail. Muddy shadows, BTW can not be compensated in printing.
