232111 - Architect PR for Australia

Hello

I have 10 years of experience as an architect (2005 - 2012) & (2015-2016). I’m planning to apply for PR for australia with the code 232111. How many years of experience i can project in this case? Only last 10 years will be considered and should not there be any career breaks? Also if i have 75~80 points, would it be good enough to get the PR? looking for some guidance here.
