xp rates

Post your data regarding xp rates

for pure essence, 42 essence per trip

Start xp End xp Difference xp per ess
425635 426152 517 12.31
426152 426712 560 13.33

12.82 average xp per ess, so 6.41 base xp before zmi 2x xp

for daeyalt essence, 42 essence per trip

Start xp End xp Difference xp per ess
426712 427572 860 20.47
427572 428436 864 20.57

20.52 average xp per ess. Assuming its base*2*1.5, that would be 6.84 base xp (a little above average). I have much more data agreeing with this value but its 2am and I need to get to sleep

If it was base*2+base/2, you would have 8.21 base xp, which is much further away. I should be seeing around 16 xp per ess if it was this way.

Wow, this is super interesting! You made me do some more research, and it turns out our documentation on the ZMI altar has been wrong this whole time (nearly 4 years!).
Should the Ourania Altar, also known as the ZMI Altar, be introduced into Old School RuneScape? The Ourania Altar would allow you to craft pure essence into a random selection of runes, providing double the usual XP for each rune crafted.
Per the poll question, pure essence was supposed to give double the base experience per rune. Instead it only gives 1.7x, and with the 50% boost from daeyalt it becomes a ~2.55x multiplier (hence the additive vs multiplicative confusion). There may be a flooring step inbetween the two multiplications, pulling the effective rate down a tiny bit.
Thanks for the data!

That would help explain why we got different results! Ill probably do a little more testing later today, but this seems very likely to be true. Piratemot (talk) 13:14, 5 June 2020 (UTC)

I'm seeing higher than 2.5x base xp using daeyalt at zmi:

Starting XP Ending XP XP Gained Essence used XP per essence
677440 678311 871 42 20.74
678311 679151 840 42 20.00
679151 680042 891 42 21.21
680042 680915 873 42 20.79
680915 681748 833 39 21.36
681748 682629 881 42 20.98
682629 683506 877 42 20.88
683506 684307 801 42 19.07
684307 685167 860 42 20.48
685167 686040 873 42 20.79

For comparison, here are some runs with pure essence:

Starting XP Ending XP XP Gained Essence used XP per essence
686040 686615 575 42 13.69
686615 687218 603 42 14.36
687218 687800 582 42 13.86
687800 688136 336 23 14.61
688136 688713 577 42 13.74
688713 689286 573 42 13.64

Taking the average of these two sets of data, I get these xp values per essence Daeyalt: 20.63 per essence Pure: 13.98 per essence

[Daeyalt / (Pure / 2)] = 2.95x the base essence xp at zmi.

This makes me think the daeyalt's 50% bonus is being applied to the entierty of the 2x zmi multiplier, resulting in a 3x multiplier compared to base rate. Ajdj (talk) 20:16, 6 June 2020 (UTC)

Ajdj, I beleive you are slightly off in your thinking of it.

the xp per Pure essence was always thought to be: base xp * 2 = zmi xp

However, Towelcat found that the 2x multiplier was always 1.7x and no one noticed.

Correcting the formula you had before would be this:

[Daeyalt / (Pure / 1.7)] = 2.51x the base essence xp
