For what its worth imo 2 - 5

 

Change with changes in emvironment (abmormal wind direction, surrounding cover, protection, etc increse/no changes or abnormal conditions decrease)

 

How long is a piece of string :confused1: (appart from exactly twice as long as half its length)

I reckon on few of the 100 lasting 5 years so at 20 per year all 100 would be gone after 5 years.

 

1st year 20% failiure rate from total population.

 

2nd year 25% (80 remain so 20 from 80=25%)

3rd year 33%

4th year 50%

5th year 100%

 

as time increases so does the probability that a greater proportion will fail.
