This is what happens when some kind of new compound is formed between these two, here it'll be series of sulfuric acid-water complexes. Same thing happens with metals when intermetallic compounds form, see titanium-nickel phase diagram. Normal case would be eutectic, see aluminum-silicon phase diagram

Some of which are probably only a bit stable and so only exist in a mixture

Never mind between 80 and 90%, WTF is happening at 42.5%‽

There's a metastable phase somewhere out there and change of the most stable solid phase between 4-hydrate and 6.5-hydrate
