Unless you can walk into the gym tomorrow and pull 200, I wouldn't use that for your program. In fact, it's best to be on the conservative side. I would use 180. Yes leave 1 in the tank, but that should mean you're still hitting the numbers I mentioned before. For example I managed 10 last night for my 2nd week squats, and could have dug in for perhaps 1 or 2 more.
You need to have some slack in the program so you can hit these numbers, otherwise you'll stall quickly.
5 reps in week 1 is pretty bad, 10-11, or 12 if you're going all guns.
If you look at your spreadsheet you should see your calculated RM (from the + sets you do) to be around or above your RM you entered for the program.
For example 155 x 5 is a calculate RM of 174, yet you are using 200.
My week 1 I did 175 x 10 which is a caculated RM of 233, and I'm using 230 for my program.
