I'm just going to say no. Pretty much anytime someone has asked to do more weight the answer is don't. The point is to make progress doing a bit less than you can on the assistance so in this case it would be 195 for 5 sets of 10, if that's easy good it means your strong. As far as the extra sets of 405 it might depend what they looked like, if the last was like a 2RM it probably wasn't a good idea.
You might be capable of doing all that extra weight/sets now, but there are four possibilities here long term
1) You don't improve, you can only blame not following the program
2) You improve but not because of those extras, so it was just wasted effort
3) You improve but eventually hit a wall because you gave it 90-100% too long and can't maintain that forever
4) You improve by what your doing and only because of those extras, your smarter than everyone and should write a training book.
