I'm looking at the 5/3/1 Building the Monolith LiftVault spreadsheet. I inputted my 1RM for my bench press as 105kg. On Wednesday, Week 6, it tells me to do 90kg for 5x5 across. What? That's insane! I'm confused. Am I actually supposed to attempt that for 5x5 or is that some kind of rounding error?

You're supposed to use a training max, I think it's 85% of 1rm for BtM? So for a 105kg 1rm, TM will be 89.25kg. After 3 weeks you add 5lb/2.5kg so your TM going into week 4 would be 91.75kg. Week six should be 5x5 @95% so 87.1625kg.

I don't think you've looked at the spreadsheet. Week 6 Wednesday is 95% of my TM, rounded up. My TM is already 85% of my 1RM. 1RM is 105kg. TM is 90kg. +2.5kg TM is 92.5kg after Week 4. 95% of that is 87.875. The spreadsheet rounds it up to 90kg. So, the issue is that the spreadsheet rounds up, when it should round down, but that means the entire spreadsheet is wrong. I can change the formula for Week 6 Wednesday bench, and I will, but that begs the question: what else do I have to change? Where else should I make the spreadsheet round down instead of round up? Everywhere?

Just keep the website on hand and do a quick calculation before you hit the gym that day to make sure you've got the correct percentages. If you want to stay conservative with your lifts, you can always use the formula "=FLOOR" to round all the calculations down in your spreadsheets. Do it once for everything and you'll never have to do it again. Won't take longer than a few minutes if you're using the spreadsheet from liftvault.
