Its a nasty short cut to get more oomph out of your machine instead of cleaning it up and doing a proper job.. it will eventually kill your machine... no reason to go high tap at all. its an insidious act of vandalism that some tag "restored" to.. nothing could be further from the truth.
LOL- needless to say im not happy with this technique of tweeking a game 
100% agree !!
If the game was meant to play faster, it would have left the factory high tapped.
I refuse to do it on EM restos, as guaranteed with 6 months - I'm told that plastics are broken or the ball keeps smashing into the glass after a target reset.
I'm no fan of tweaking EMs in this way - but if it is your machine - you can do as you please.
