ZT are my weights correct and method (posts #7&#10)?

Personally I would mix and steep in a larger necked container .. then split it up after steeping

however Im probably mixing larger batches than the average home mixer .. which might render this pointless

so yes .. mix in a glass pouring beaker (dont trust the measurements on these .. they are notoriously inaccurate .. get Grade A Measuring cylinders for real accuracy when making your initial weight / amount observations and writing them down for future use.. and even then my interpretation on where the line is in relation to the liquid may be different to yours (but that is defo splitting hairs)

tip 2: when pouring out of your glass beaker .. get as much as you can out .. then stand the beaker in warm water for a few minutes to get even more out ... there will still be transfer error (the liquid that sticks to the glass - the error is larger the larger container you use, this happens even with water, the more viscous the liquid, the larger the transfer error) - this is why weighing into the final container is the most accurate way) but warming the last bits up will minimise it.

You need to change your username to "GuruZT". This is fantastic advice, thank you.

In terms of the official written scientific word I suspect so (the nic base and flavours will vary slightly from straight pg - however at smaller amounts i very much doubt its anything to worry about)

however like I said earlier .. I have noticed variations even amongst different batches of base fluids - so i always pre weigh known amounts of mine (grade a measuring cylinders on scales) BUT .. I'm exceptionally OCD and anal about it .. its probably not at all necessary and i am using a VERY accurate set of scales and large quantities (the larger the quantity the more small variations will show)

If you want to exactly recreate something you've mixed in order to improve it, of course it's important. Unless of course you're a "That'll do, tastes good enough" sort of mixer or just have crap tastebuds, in which case this is the wrong thread for you.

I wasn't having a go at anybody. It's just that if you put the same liquid in 10 different tanks you'll get 10 different flavours, change the wick or coil and the flavour changes, get out of bed the wrong side and the flavour changes - a slight variation in the VG or the amount of nic or concentrate isn't going to make any difference.

Do you all calibrate your scales and test them with a certified weight?

Digi scales do have a worryingly habit of wondering off by varying amounts......

I use pretty hightech and expensive scales in work, and even after a short period of time they have a tendency to lose/gain +/- .2 - .5gramms over the course of minutes....

We check and re-calibrate after each mix to ensure total accuracy....

Yes this also .. everytime I turn them on

Although there is some question as to wether the calibrated weight has to be calibrated (mine is) - if its a few grams off but you always use the same weight .. shouldn't make a difference .. it will be kinda calibrated with itself.

The problem then is the fluctuation (?) of the +/-

The .2 - .5 'swing' is actually quite a big amount if your using small quantities.....the only 'true' way to measure the correct weight is to check weigh the scales with a 'stamped' weight (sorry.....this is what i meant when i said "calibrated")

If you know that the weight that you are using to check your scales is correct and and "absolute" then you know your "actual" weight is accurate and correct

Temp/enviroment are known factors to affect electronic scales......

Thats totally true dat

is why I check them every time I use them, using a proper calibration weight at a weight my scales calibrate at. The calibration weights themselves are an outrageous amount of money!

Just as some input I recently bought some digital scales to measure out the ingredients for a bad ass home made pizza I made. Anyway... It has an option to measure in mls so bang an empty 10 ml bottle on it, set to 0 and away we go. It was only 15 quid from argos
