Anyone forged a Mage Shield recently? (in General)

Ok so I have been forging my Mage Shield for about a week now, small bits at a time and I began to think that there was something wrong...

I have been using the same formula from the wiki (and cbstuff) which is 120 , 22.

Now I have done some testing. With the 'perfect' formula you should get RPM gains of 2:1:5:2 which is 10 'parts' total, or 100%.

Now for the formula listed above, these are the gains which I received, with the total percentage last in the list (the only result which is listed in %) and yes I know, I only listed 3 measurements because so far I only have 3 of them:

1,761904762
1
4,972789116
1,986394558 totals: 97,21088435

1,780821918
1
5,006849315
1,780821918 totals: 95,68493151

1,761904762
1
4,414965986
1,768707483 totals: 89,45578231

Now, if there is a small error in the RPM gain which is 1 (which is from the cooling after first part) then the first 2 results are still reasonably well.

Though the last result gives only ~89% RPM instead of ~100%, thats 10% you haven't received...

I tried a few different times and found the following (both 1 full cycle)

115,22: totals at 89% also, this is due to the first time being a bit too short
0,890410959
1
5,006849315
2

125,22: totals at 92%, not due to the first time but the second time gives a different result now, also you use 2 more BA for this and it doesn't give better worth for your BA now...
2,006849315
1
4,452054795
1,773972603

I will be doing more testing coming week and hope to find out what is either wrong here or is happening...

Forgot 1 thing: if you are forging a Mage Shield and want to help, here is what you can do:


Keep very close track of the formula you use,
Keep very close track, and note down, the RPM gains you make,
Calculate the pure RPM increases you gain (which is rpm2-rpm1, rpm3-rpm2, etc),
Divide the all RPM increases by the second increase,

you should now have 4 numbers of which the first and last should be at around 2, the second should be exactly 1 and the third should be at around 5.

Either make a spreadsheet and send it to me or post your RPM increases here so I can file it.

Thanks,

The best way to check how good a formula is, is to use NW/BA. You can then easily see how effective each formula is. Keep in mind that you don't necessarily need to be in the sweet spot, if a formula uses less BA it may end up being more effective than a formula that uses more BA and that does lie in the sweet spot. The AoAC is an example of that.

As to your results, forging has a large random factor to it, so anywhere from 90%-110% is an acceptable range. Over the long term, 125,22 will be much more effective. Do multiple cycles and average them out to see that.

I know all of that.

The problem what you say is indeed the NW/BA

with 120,22 you gain RPM/BA (which is NW/BA) at 3.3 or even 3.4
with 125,22 you gain RPM/BA at only 2.98

This makes quite a difference...
