Im in Europe.
I use the 6x10 nearly all the time.
I have my recovery delay at 50 - 60...
Recovery delay isnt everything involved in a fast recoveryspeed. Lets take the XP goldmaxx power as an example. It is known to have a very fast recovery speed. The disc knob on the GMP stops at coke. You can only disc out iron and coke...
To obtain the best recoveryspeed possible You can not disc out all the iron and coke.
As with the MXT where the disc knob is best set at 1,7-1,9, not any higher.
Or the new goldbug where the iron split tone is best set at below 20 to obtain the best results for discoveryspeed.
On the V3 I get good recoveryspeed when i open up the disc window from - ( minus ) 30 with the same tone as all + ( plus ) numbers. It is not annoying at all cause there is not many trash items hitting solid there anyway. This setting helps the machine to see the low conductors better as the window from disced out and to the ID of a solid 12 for excample now is 42 and not 12 as it would have been with all iron disced out.
Its not a secret and most people using the XP use this kind of setting but do not realize why the machine gets a better recoveryspeed from it.
It is just that way with any machine.... Make the window bigger and your recoveryspeed will be faster without losing depth.
