The old rule may not be adequate. ‘Hydroplaning of aircraft tires‘.

“It is concluded from this analysis that modern tires have lower hydroplaning speeds than previously assumed.”
Also re the accident, whereas a wet runway / hydroplaning might have led to the poor deceleration during the latter part of the landing, it is also possible that a change in runway surface would give similar indications. Note the the report’s discussion of minimum runway surface friction and ‘slippery when wet’ (page 15) and the aerial photo of the runway (fig 9, page 16).
