I tend to allow everything to go down a couple of seconds in the first instance, to allow for a bit of on-site adjustment if required.

I dont see the point in being unduly restrictive in 2500’s as the way I see it, it is the designer and the maintaining engineers responsibility to make sure that everything is safe. By all means have default values that will take over if the RAM is cleared for whatever reason, but reducing the options available on commissioning or if things change a bit in the future just makes for extra work if you have chosen to be a little over-cautious when calculating the intergreens and setting limit values.

But then again, Im also not averse to setting intergreen levels lower than 5s either, especially when there is no clear reason to by virtue of geometry.
