Not simply, but yes, there is a second-order 64-bit architecture effect.

Basically, on 32-bit architecture the registers used for integer arithmetic are 64 bits wide. Numbers less than 264 can be operated-upon by a single integer instruction. When the numbers involved are greater than 264, so that they are 65 or more bits long, integer arithmetic operations on them have to be performed by two or more instructions, _plus_ instructions for combining the 64-bit result parts (e.g., carries from the low-order part to the high-order part) appropriately.

So far, this is true regardless of whether the underlying architecture is "32-bit" or "64-bit", because it depends on the register width, not the bus width or address length. Perhaps the "64-bit" architecture enables 64-bit integer arithmetic registers to operate somewhat faster, but that wouldn't change the fact that a 65-bit number would require _at least_ two instructions for each integer arithmetic operation.

However, "64-bit" architecture probably has 128-bit-wide registers for integer arithmetic. This allows a 65-bit number to be handled in a single integer arithmetic operation instead of two or more, and thus eliminates the more-than-doubling number of instructions for numbers greater than 264, compared to the instructions needed for numbers less than 264.

So, you see a more-than-doubling jump in time when going past the 264 size of numbers on 32-bit architecture that has 64-bit integer arithmetic registers (or on 64-bit architecture that has 64-bit registers), but not on 64-bit architecture that has 128-bit registers.

OK, then I'll wait some weeks before updating Team_Italia stats.

Though I was sure that some PW handling could be done from server side (like deleting a Team and recreating it). I'll be living with it, waiting to know which updates may be done from team pages.

Now, the last question:
3 - Once a user has joined a team, is it possible for the user to still see his personal stats ranking together with team stats ranking?

Don't bother to answer me if the answer has to do with the team pages work...

Thanks George!

First time I read PHP but I think I can, especially with code that is so well documented. To be able to use that piece of code one needs access to the table "t_gimps_credit_timings".

And shouldn't the P-1 credit be the difference between the P-1 work already done and the reported work ? Or is that part of the code in another module ?

That's the cheesehead bug. You can pad your P-1 stats (until you're caught and I manually zero them :)

Remember P-1 is really only supposed to be done once.

I found the way to adjust text colors in Firefox, so will try to remember not to complain about colors again.

I think this is a good reason to get rid of the menus completely. Firstly, they don't work without JS. Secondly, they hide links forcing people to click multiple times to find the link they really want. Thirdly, even with all the menus open it still doesn't fill an entire page height so they are not allowing people to see more that might otherwise "be lost" below the screen. Fourthly, after opening a menu item and clicking on a hidden (now exposed) link then the next page will collapse all the menus again (very annoying).

I wonder what problem was being solved by the addition of the collapsed menu items? I hope it wasn't only added just because it could be added (or maybe even because it "looked nicer?).

I vote to restore the fully expanded menus items (no JS please, it is just not necessary). With all the items shown it would much easier to find what one wants without having to click everywhere to expose links.
