I am certain there are many IV and IV-P pilots out there with more experience than mine (100 hr on type, 1000 total time) but I have been trained by some fellows who have a lot more flying experience, and they clearly determined two speeds were too low in the POH and the PTM training manual which many may have read.  First, a caveat about our experience.  When doing stalls in training, we found our IV-P did not stall at the book value of 61 Dirty, rather more like 66 Dirty and not at 69 clean, but more like 75 clean, so this impacted our thinking.
 
The first was rotational speed.  65 as per POH was too low, too close to stall for safety.  I was taught to start lifting the nose gear up at 75 - 80 and let it fly off.  When fully loaded, 90 is my speed to begin lifting the nose gear.
 
The second was base and final approach speeds.  The book speeds were too low for margins of error, so in circuit, it is 120 on downwind, 110 on base, and only 100 on short final, 90 over the fence.
 
Hope this helps the discussion.
