Latest version
of VWF Software

As per January 9th 2017 the latest version of the VWF Software is version VWF 4.21 inwhich the Export-function is included. The Export-function has 2 options viz. exporting to a plain txt-file or exporting to a csv-file inwhich the the 2 summation formulae are being preserved. Version VWF 4.21-UPDA is a VWF-update version without Mento-Factor Compact. For analyses with MF-C it is necessary to analyse with a previous VWF version.
The Manual on the VWF Software is also modified.

VWF 4.19

Recently, October 2016, it was found, almost by accident, that there was no Export-function in VWF; viz. to import a VWF-analysis via a .csv-textfile into an Excel-sheet for further processing and analyses, as is the case with RWF and BWF. As from November 24th 2016 the Export-function is included in VWF; it even entails the simple formulae for addition.

VWF 4.17

As from November 1st, 2014 a new version of VWF is available. Some improvements and additions were made.

VWF 4.16

VFW software including MF-C

As from February 10th, 2014 a new version of VWF is available. Some improvements and additions were made, a.o.
1. The special analyses named code 0-0 like R + Gr and Gr + M and Gr are now available under the added 3rd option of
   Grasp named “grasp code 0-0”.
2. The slide grasp must, as usual, be analyzed as a Move over the transportation distance, where under “description”
   the grasp type can be indicated.
3. The option to append an other analysis to the analyses at hand and move it within the analysis, is improved.

VWF 4.08

The WFGD has released the VWF version by VWF 4.08 in September 2013.

VWF card for the USA dd May 2007

For use for our American VWF users, a VWF card has been made onwhich the various values and measures are expressed in inches, ounces and yards. These values are tested against the values as used in the original RWF manual USA.

VWF cards dd 2007

New VWF cards have been made, because the new VWF 3.02 software made us aware of the older cards. Now, yoy may order cards in dutch, german or english.

VWF course choice
dd 2006

Until now, the VWF courses were based on analyzing manually, this means that the VWF analysts-to-be were educated and trained with aids as the VWF manual and the VWF card, inwhich the VWF times are rounded to a multiple of 5 VU.
Originally this was meant to be so and organized.

With the arrival of the small and fast PC’s and the possibility to develop easy-to-use software for the VWF system, the necessity for rounded VWF times to a multiple of 5 VU for “easy to calculate” purposes vanished.
Through the development of new VWF software, VWF3.02, and after contacting numerous VWF analysts, the WFR decided to also publish a VWF manual and VWF card for analyses on the PC, so for non rounded times.

On the customers request or for the VWF instructors own reasons a VWF course can be based on VWF manually or on VWF PC.

Demo version of VWF 3.02 dd 2005

To be able to give every VWF analyst the opportunity to get acquainted with the new VWF 3.03 computer software, the WFGD has decided to release a demo version. This demo version has the full functionality of the VWF 3.02 program except for the print and storage function, which are turned off and of course some limitations in the number of analysis lines.
Analists interested in this demo version of the new VWF 3.02, may order this demo by sending an email with the request to the secretariat of the WF Council.

The small costs of the VWF demo version are € 13,=, as a small refund for the expenditures made. When the program VWF 3.02 is really ordered these costs will be subtracted from the price of the VWF 3.02 software or refunded.
