There are many variables involved, from age to bodypart weaknesses to a lifter's form.
Just to add to that, it helps with these things not to even consider percentages. Just go by feel and start with 'easy' singles and do multiples from that. I know for me, multiple singles at 90% in a lift such as the Squat would still kill me and I'm pretty well inured to singles and to higher volume. So 90% can effect people differently and is also different when comparing lift to lift.
An aside; what I've found with higher volume training is that you don't always have to fill in the volume with the same lift. A nice variation I have been doing has be to work upto a daily max in one lift, say the Squat and then perform back off sets in another similar exercise such as either Partial Squat or Front Squat. That is a nice way of racking up volume while either focusing on a weakness or safeguarding an area, like the knees.
