Hey man, nice workout. Now that you know your current 1RMs you can space out your warmup lifts better, leaving more juice in the tank for the one that counts.
The lower difference between workset and 1RM on the deadlift is normal at first. Maximum effort is a new game that requires ultimate CNS coordination and will take a few goes to ease into. Also bare in mind that you are comparing 5RM with 1RM, while squat is comparing 3x5, so the difference will more likely be larger at first.
You probably feel the same way I do about bench... I have never managed a 1RM more than 10% of my 3x5 workset on bench, while squats and deadlifts have peaked at 15 and 20% respectively. It's probably normal...
Take a step back and reflect on what you've just lifted and what your thoughts would have been walking up to a bar that ladden with weights 8 months ago. I hope to join you on the Texas Method in the not too distant future!
