@freeflowme and everyone else,
I'm not quite sure what the issue(s) is/are here. I've tried reading the last few posts here and watching the video.
There are a lot of ways to structure 5 deadlifts at a given weight. They all have their pluses and minuses. If you're completing a deadlift that would get white lights at a meet, you're following the program.
All the talk of CNS fatigue notwithstanding, the deadlift is the lift of choice for PTTP largely because of its focus on the skill of strength. The way the deadlifts are taught is directed at both people who are new to deadlifting and people interested in a fresh perspective on the lift. It is common at StrongFirst courses and certifications for half or more of the people in the room to achieve a new PR while at the course because of the way we teach strength. Those kinds of instant gains aren't the result of hypertrophy.
If you're tiring yourself out, you need to rethink your choice of weight or your technique or both. No one should be spending a lot of time in the range of 1RM that would cause undue CNS fatigue.
@freeflowme, I cannot comment on what Starting Strength suggests, but I can suggest that you pick their approach or our approach and follow only one of them. If you want to ask questions about their way, please go on their forum to do so.
If standing up and resetting between reps doesn't work well for you, there could be a variety of reasons. If you watch
@Anna C's video, she is calling that a set of 5 and what you do 5 singles. I would call what she does either one - it doesn't matter. She is resetting at the bottom.
What PTTP recommends isn't singles where you drop the weight and walk away from the bar but rather singles where you do essentially what you see Anna doing, but you stand up, do whatever you're going to do before a rep, and then bend down and pull again. You'd be doing something closer to her timing than the timing I saw in your 265 x 5. Most of your time in a PTTP cycle shouldn't be so heavy that you cannot perform a set of 5 with a reset between reps that's essentially a single breath, maybe 2 or 3, but not more than that.
Note that the PTTP approach of not performing a controlled lowering and of resetting at the top most of the time is perfect for improving your 1RM and also for keeping the focus on skill and not hypertrophy. And let's not forget safety - slowly lowering a deadlift is where many people get hurt because it is a specific skill one has to acquire, and that skill isn't what PTTP focuses on since the lift isn't performed that way when testing for a 1RM.
When the weigh gets heavy, the volume will be lower - people don't pull sets of 5 at 90% of their 1RM as a rule. Longer rests with heavier weights makes sense.
I hope I've addressed some of your concerns - holler if anything's not clear or if you want to continue the conversation.
