Good news and bad new. I was going for something similar to what 
you have above and both slash the time alot:

Time (s): 1.024

But now the output is a little garbled. For some reason the 
splitter isn't splitting correctly - or we are not applying it 
properly. Line 0:

N.A.|4.875|207000|3", "0", "03/200", "|05", "2009|75", "75|1|26", 
"80", "|N", "|", "O ", "ASH", "OU", " REFINANCE|PUD|1|INVE", 
"TOR", "C", "|801||FRM", "\n\n", "863", "", "FRM"]
