Math equation for calculating how much herb you have smoked out of a piece

greetings cannabis community.
I was high as balls the other night off of some dank Blue Dream and i had an idea that was so amazing that i cannot Believe i could comeup with it. Ready to be MINDBLOWN. TRY THIS YOUSELF, its a practical application of your boring math.
So I created a math equation to calculate the approximate amount of marijuana smoked through a certain bowl/piece/pipe since its last cleaning. Bear with me, the equation looks complicated, but it is really simple. Needless to say, i was stoned off my ass to come up with this shit
Here it is:

(Bf-Bi) = H = Tw
...Bg......Bp

Bf= the bowl's weight in grams with the resin in it, its current weight. (65.5g in my case)
Bi= the bowl's weight in grams when it is completely clean. (63g completely clean of resin)
Bg= the mass gain of the bowl for every bowl packed, which i calculated to be an average of .02g of resin per bowl smoked.
H= the amount of hits taken since last cleaning, (65.5/63)=2.5/0.02=125 hits in my case, no units since the grams cancel out.
Bp= the mass of each bowl packed, my bowl holds a .1g on average.
Tw= the total mass of the marijuana consumed through the piece in grams.

Sooo..... We plug our numbers in and we get this:

(65.5g-63g)/0.02g = 125/0.1g = 12.5g of weed smoked since its last cleaning. And i have to say, that it pretty goddamn accurate. Try it out and give me your feedback brosefs!

How did you determine the 0.02g/bowl ? And is it variable with total quantity consumed over time?

haha this is dumb as fuck, not all weed is the same. It's as simple as using a scale you fool. weigh stash when you bag it or buy it, weigh it later when you're curious and VIOLA.... bahaha

i used my scale (0.01g accuracy) and weighed it after each .1g bowl and it was pretty much +.02g each time, so i used it as a constant
"Pretty much"?
First off, your scale immediately has a +/-25% error at that measurement. That error propagates throughout your calculation.
How many measurements did you make in determining that 20mg constant?
