You really do need 40 minutes if it' is a A380 at T3, the gate is some distance.
If connecting from another flight it is different.
Thanks for the ever valuable response CWS - I am starting to think you actually have a PhD in Airline Operations! I would be starting from LHR, so sounds like 40 minutes is the minimum. Should be doable in this case, but only concern is getting passport/visa checks etc in time - was not entirely sure if this fell within the T-60 check in closure, or the (in this case) T-40 security clearance. Hadn't realised that there would be different rules for T3 and T5...
