Nice and helpful article - Thanks. Just Curious...

To select eligible candidates in the first select you say

select * from @Candidates where MeetsEligibility = convert(bit,1);

Why do you convert the 1 into a bit? just saying 1 works. I know that the data type for MeetsEligibility is a bit and I'm just curious if there are efficiencies is converting explicitly like this or is it just a readability thing?
