the crucial times for me I find is when you are first attaching a system and the first couple of hours at least afterwards. If ur hot and sweaty during attachment or soon afterwards ur bond is going to hell.. If u attach one day and its dry and u get a good attachment and the next day you start sweating or hot.. Ur probably gonna be fine. Especially if your using a stronger adhesive. But it just really sucks when ur body temperature is too high when u attach..

being in a cool place isn't always the case. There will be times when your on vacation or somewhere.. and whats worse is once u start getting frustrated or panicking,, U sweat more and its a downward battle.
