That's not comparable at all, sorry. R5 have 32 mm restrictor and there is no chance that R4 would get same or even bigger one as it would make no sense. The aim of creating R4 was to replace N4 not to add competition to R5. Based on the rumors the contrary is going to happen as it looks like R5 will be made even faster (and more expensive).

By the way from 32 to 34 mm is roughly 10-15% of extra power which is quite huge difference.
