Stall speeds and safety
With the posted numbers it really looks like there's something wrong with the pito lines and/or ASI instrument.
Vans published numbers dirty, are 49mph (42kts) light, and 55mph (47kts) heavy.
Our 6 ASI reflects those published numbers.
For safety considerations in any plane new to me, I do slow flight until stall indication. In small planes I'll let it buffet or drop a wing, then document that stall number.
Trust, but verify the numbers!
After confirming, when low I always fly at least 50% above VSO combined with max bank of standard rate turns or less until stabilized final.
Then VSO plus 30% (Vref) on final bleeding off some more if the winds are light and the field is short.
It's just tragic to see so many general aviation "slow and low" accidents happen that could be avoided with proper speeds and bank angles
