Reviewing the results you notice a discrepancy between the k-factor of an equivalent k versus a sprinkler head using that equivalent k-factor

In the example below, EQ02 has a k-factor of 5.37.  Reference point 1 is supposed to use the k-factor of EQ02 (5.37) but in fact is using a different value (5.36).

Calculation stops at Step 1a.4 - calcing total lengths

There is also Runtime error 5 invalid procedure call or argument
