I have been running boinc for a while now and i usually update projects manually in morning or night or sometimes both since there are usually 10 or 15 results ready to report...so i started to wonder..do most people update manually on a regular basis...is this a good or bad thing to be doing?...any input appreciated.

BOINC will automatically report the to be reported tasks, but it does only do so at least 24 hours after the first task was ready to report. Why not do so immediately? Because it adds to the server overhead.

Reporting 1 task takes as much overhead (database reading and writing, memory usage, CPU usage) as does reporting 10 or 20 tasks. So it's more efficient to report multiple tasks.

So, then, completed work is reported at the first of:

1) 24 hours before deadline.
2) Connect Every X before deadline.
3) 24 hours after task completion.
4) Immediately if the upload completes later than either 1, 2, or 3 upon completion of the task.
5) On a trickle up message.
6) On a trickle down request.
7) On a server scheduled connection. Used, but I am not certain by which project.
8) On a request for new work.
9) When the user pushes the update button.
10) On a request from an account manager.
11) Report immediately every task, if "No new Task" is set.
12) Report immediately if CPU or network time-of-day override starts in the next 30 minutes. (BOINC 7.0)
13) When minimum work buffer is reached. (BOINC 7.0)

I'm not saying you should stop updating, that's a decision you can make perfectly well for yourself. I'm just saying that BOINC will do it automatically.

What cache settings are you using?

Boinc 7 has a new scheduler, it'll cache an amount of work adding up to the Minimum plus Maximum watermarks, then wait for the cache level to drop below the Low watermark before asking again,
having a 2 + 0.01 cache (as opposed to 0.01 + 2 which was used in Boinc 6) will get you more often reporting.

Thanks for info i have been letting it just do its thing last couple days and seems to be doing fine other than lots of reports always being ready. @claggy i am not sure exactly what that means but if you mean the min work and additional work setting i have it set to 2.0 and 2.0. The default was 5.0 and 5.0 but it was downloading too much work and couldn't finish some of the tasks in time so i lowered it after i saw this was happening often.(using 7.0.28 on win8 x86 64 bit amd 6core processor.) Seems like i am averaging about 15-20 completed taks that are ready to report.
