I don't want to appear to be arguing with you but I don't believe any of the SIDs issued by Cessna on the 100 series are driven by experience.
They are the result of assessing where they think there may be failures. If Cessna are so good, why did the 162 need a major mod in the early ones?
How many fatal accidents in light aircraft are caused by structural failure due to corrosion?
Prorgrams and SIDs written by the manufacturers for those old aircraft are simply product liability CYA actions. No-one expected aircraft to last this long and the prospect of liability on a 50 year old aircraft must cause them sleepless nights.
