I forgot to ask what sources you are using that describe the two methods...

I have another manual that states one drop should follow another every 10-15 seconds...so this is a third method for us to throw into the mix....as follows...

One drop every second
One drop every 10 to 15 seconds
One drop every 20 seconds

The same end result will not be achieved by the above methods....
The difference in timing will be there but very small
You are correct in saying that these values are not the same...
The same Timing values are not acheived by the above three methods...

It would be interesting to see how much difference in dynamic numbers would be between the three methods....If I ever get the timing equipment I will get values for all 3 methods ...

I find the same type of difference in manuals describing valve clearance numbers...all a little different but all very close....
I love this forum...it keeps my simple little brain fully engaged...

I hope some other forum members can jump in here to help us on our search for truth and understanding of this mystery....Barry???...Brian..???
We need help here...??!!
