NO, no no, the MAXIMUM time permitted for OPT is 1 year.
It has nothing to do with the validity period of the visa which itself is meaningless.
You also have to complete 1 full year of academic studies before you can become eligible for OPT. So you cannot just waltz in, do a few months of training - then expect to get 1 year of OPT chucked in. it doesn't work like that.
You are also making assumption of the potential number of hours that might be accumulated. You need to factor in some potential gotchas here..
