# Do manual and electronic machines maintain tension better than drop weight machines?

I just got back from my local tennis shop, and the guy at the desk and I were talking about stringing machines. He told me that the same strings strung at the same tension by a drop weight machine and electronic machine play identically for the first hour or two but the strings strung by the drop weight machine lose tension much faster than the strings strung by the electronic machine. Is this true or is he subtly dissuading me from stringing with a drop weight so that I come to him for stringing?

'he subtly dissuading me from stringing with a drop weight so that I come to him for stringing?'

That's all I can think of. I'm no jeen-yus, but I don't see how that logic works.

it doesn't matter if a string is pulled at the same tension by a drop weight, electric machine or even by hand! Why would a racket lose tension faster than by any other means?! Your racket and strings don't know by what method they were being pulled!!

It is subtle BS. Leaving out LO, reference tension from any calibrated machine will be the same. That is true for the basic DW to the high end eCP. What may be different could be the final overall tension due to differences in technique and equipment. I mean you could have drawback from the basic DW that does not exist to a significant measure on the eCP. However, if for example RT is used to measure final overall tension for same string in same frame and they both say the same tension, then the frames have the same overall tension in spite of the machinery. To say that one will lose tension faster than the other is not valid except under certain conditions involving static tension loss. If you pull and clamp quickly with the DW vs a slow pulled eCP, you could end up with different tensions. Or you do a fast eCP pull and clamp vs a long pull on the DW. However, I suspect that the end results will not be the same using RT since there is different static tension loss due to creep. Doing it this way means the stringers have different technique and is not a valid comparison. 2 cents.

What the pro is saying is that (perhaps) his machine/technique removes more of the static tension loss than the amateur using his (same) machine. My answer would be 'so, I get the same reference tension with less static tension loss? How can that be if they both end up with the same reference tension?' I would laugh at this assertion.

Yeah it smelled like BS. I'm glad I did my due diligence.

Whether a racket is string by a LO, DW, or an electronic machine the same result can be obtained from each. You can fool some of the people all the time, and all the people some of the time. You can't fool all the people all the time.

When tensioning a string let's say it is stretched to 105% of its original length. Once it is no longer stretched and tied off no matter how it got to 105% of its orginal length does not matter.
