instead of using hardy have u thought of using ditra matting
prime chip board apply flexi addy on 4mm bed roll in pre prepared ditra matting staple down with galvenised staples. i use this method for past 10 yrs. if the floor is uneven skim over the matting with flexi leveler such as weber flex. as i do most of my work on a price basis this method takes about a quarter of the time it takes to put down hardi. also the matting acts as a dpm and is totally water proof use shulter tape over joints. ideal for wet rooms

5 yrs ago had a contract for 52 wet rooms every one the same green chip board floors and walls tanked every one with ditra and kerdy matting had to give 3 year guarentee.the tiles we used were 25mm mosaic 3mm thick consulted with shulter for advice. jobs done. zero failures. the germans have been using these systems for years.it also reduces the hight of the job nothing looks worse than a large step up on to a tiled area

why holds the matting down when get to end of roll. using a decoupling membrain is a far better method than using a backer board on floor substrates which have deflection and movement

I was under the impression a decoupling membrane was for lateral movement and not deflection..?

If anything Hardie backer glued & screwed to the deck will make the floor more rigid than a bit of Ditra.
Hardie state that their boards offer no structural strength but they certainly help the floor & make it feel more secure.
 
I'd be intersted in this method Ray, but in my opinion it just doesn't sound right....because most new builds joists are not at 300mm centres and more than likely 400+
Even more so the chipboard could be 18mm and it's only glued together at the ends and doesn't always land on a dwang, so putting down sutra or equivalent wouldn't meet the adhesives companies requirements for strength surely?
Also if these bathrooms do need replacing ten ultimately when you lift the ditra the whole subfloor will be destroyed too.
