I published and then removed it because I felt... silly... but because you asked here is what I wrote, I was asked to explain how I determine what settings I want to use in the Forge for the Tempest and Thermal Accumulator.
I'll focus on how how I worked out my Tempest setting & squeeze in the TA at the end.
The first step is to work out where on your device you want to heat and therefore how deep you want to put the device into the Forge's induction zone.
After setting the position, we then have to decide how we want to heat the Tempest. Do we want to heat up the Tempest quickly, which leads to a convection heavy extraction with a shorter session time; or do we want to heat the Tempest in a “low and slow” style; this style of heat up tends to increase both the session time, the radiant heat and the amount of heat, in the form of conduction, that the Tempest’s bowl experiences (this second style is my favourite and results in a full extraction). This translates into a power level setting. The higher the power level, the more heat is applied by the Forge to the device, which generally means a faster heat up time. Where as a low power setting, slows down how fast the device heats up, by lowering the amount of heat that is generated, by lowering the power that is applied per second.
How is all this useful?
Well - I noticed with a bit of trial and error; that when you enter debug mode on the Forge it maintains the power level that you select. So I set up a bunch of profiles to enable me to easily test different power levels. If you are on a profile that has the power level set at 50%; when you enter debug mode, the Forge stays on that power level which is evident in joules per second being applied to the device as below :
3000@100% - 233 joules per second
3000@75% - 172 joules per second
3000@50% - 124 joules per second
3000@25% - 62 joules per second
The above values are examples I generated when putting the Tempest into the Forge with a fully charged 3.0ah battery, the exact number of joules per second depends on the batteries charge and the device its coupling with. We can use what we have above to now try and dial in the setting’s for the Tempest.
I like the Tempest best when I do a "low and slow" heat to just after the double click. To create a “low and slow” profile on the Forge for the Tempest we pick a low power setting - I'm going to use an example of 25% - and then we switch into debug mode and put the Tempest in to heat and take note of the total number of joules of energy that is required to get the Tempest to "double click".
In the example above I’ve used the devices click discs to tell me when the device has reached the desired temperature. In this case I waited until the second click; which gives me a reading of 2428j at the power level of 25%. Now I can set my Forge to the value displayed in the previous video; however as I want to go past the "double click" I’m going to use the setting of 2450@25%.
As you can see the setting 2450@25% causes a double click. This becomes my starting point for trying to work out what my preferred setting is with the Tempest - and its actually much higher at 3000@25% but that's very specificlly tailored for how I heat the Tempest and the specific depth I place the Tempest in the Forge. I will share a photo later as I have only 5 pieces of media

** This part talks about using the same method for the TA in the Forge **
Now this is great for devices that have temperature feedback like click discs but what about something like the Thermal Accumulator which is unregulated. The easiest way to tell if the Thermal Accumulator has heated to the required temperature is to go based on the amount of vapour that is being produced, after we remove it from the Forge and take a draw. The other thing we have to consider is the Forge’s safety settings, the main one being the “Device Overheat” threshold, which triggers when the coil reaches 100c; because of the nature of the balls within the TA, which have a very low thermal conductivity, and the width of the TA which has a wider diameter, a lot of the heat thats being generated is bounced back onto the coils. For this reason we must also monitor the coil temperature to ensure we stay below the 100c threshold when trying to determine what setting we are going to use.
Anyway, here is an example
In this video it took 3422j @ 50% power to start getting to a level of vapour production that was adequate. The coil however was very hot at 97c from a 22c starting point. In other words the coils temperature increased by 75c which means that if the ambient temperature is higher than 25c you can't use that setting as the device will overheat. So I will repeat this process at different power levels until I’m finally happy with the resultant vapour and AVB.
And that's my little rant about how I tailored the Forge to my main devices the Tempest and Thermal Accumulator
** Mods, this is primarily about using the Tempest in the Forge which is why its here, if you want me to do something different let me know.
) I figured worst case it works better with a fmj or something on it and I am happy enough with that! Understanding is that changes were made for it to function better with the anvil, so that also nudged me. But really chatting with Wes from Wesley Pipes, he was just a decent ould sort so I figured fuck it! Let's roll the dice. I actually have one of the early early wands that I have been running since it dropped, so it owes me nothing 
Due to patience issues my money will go to the UK this time ^^
