Have you started using the same sound every time for EQ exercises? I picked "Acoustic Guitar" for the last few hundred K of my Diamond run - with "Vintage Trance" (soundcoin-purchased) for Bass Detective. Now I've switched to "Songs" and "Bass Guitar", respectively.
Use your chosen sound every time and you'll get to know that sound better. Pick a sound you're interested in really knowing well - or try different sounds and eventually figure out which sound is easiest for you - and go with that. I've honed my strategy for some of the exercises - which also helps.
You'll eventually want to switch chosen sounds if you want to diversify your ear more.

yes，i chose the same sound，but the problem is……in the past time，every time i pass a level can get 6—8k spi，but now i pass a level can only get 1—2k spi😷

I've been in contact with SoundGym support with suspicions my SPI for finishing a level was too low. They said they've double-checked their SPI algorithm and its working as expected. We don't know how that algorithm works - or what variables it uses to determine a score. I've got a lot less than 1-2k SPI a few times.

perhaps，the higher spi you ve got，the lower you will get，but i still wonder their spi rules

SG is conspicuously evasive on the subject of how SPI is calculated. (See attached image.) But unless you're here specifically to earn their certificate or to claim virtual trophies, it's probably a good idea to ignore SPI and concentrate only on improving at the games.

Found this discussion from 2019, https://www.soundgym.co/space/talk?id=RVGK8UAY74U&t=ZFWIJOBVLO5 Ross Williams had some detailed insights on this

I have been having problems related to the spi calculations. I opened a ticket and explained how I was scoring 8000+ points and getting 1 or 2 k . I asked if that sounded right to them. I got the same non-answer about how spi is calculated that is in their help section. Then they closed my ticket as if I had my question resolved. I can’t imagine that the spi calculation is that proprietary to the sale of this product and I can’t understand how we are to gauge our progress without understanding this metric. They promote asking my peers for an answer so I left a comment about this up for 48 hours and no one responded. I don’t blame anyone because there is no clear information on this topic.

SPI is garbage, and when you start looking into these things, you realize these clowns have absolutely no clue what they are doing. The SPI is completely arbitrary, it does NOT correlate to accurate assessment of your skill. How could it? Half of the terrible sample libraries Soundgym forces you to use are filled with noise and artifacts that you could easily use to rack up super high scores in a matter of weeks, I did it on a previous account using the piano samples. The games and this site are designed to get you to continue to pay for the service and feel like you are developing some superiority and clout on the platform by doing things like comparing you to others and implementing bizarre social media elements to the site.
This on top of them letting people subscribe full price to a beta service (tone gym) and doing almost nothing to help when you have issues, as well as a monumental lack of R&D on new games that actually improve skill (lets face it, aside from the EQ games, everything else on here is piss and doesn't actually improve any tangible skill) shows that these guys are only in this for the money.
I'm looking forward to the end of my subscription period when I can buy a single payment software that can accomplish what every EQ game on this site can do and more for less than a 6 month subscription.

Which single payment software apps are you thinking of? I own TrainYourEars 2 EQ and am happy with it.

Someones ass is burning so bright that i cant even sleep on the other side of the earth))

SPI is calculated by the 3 top scores in each game. The first score provides you x3 points, the second score x2, and the third x1. For each game, you will get higher game scores for higher levels, so when you pass levels you will get more points and your SPI will be higher.
When you reach a very high level in a certain game, you will still earn more points for the next level, but the multiplier will be a bit smaller than before. If you continue to pass levels in this game the multiplier will keep getting smaller. At some point, it is wise to focus on reaching high levels on other games to get more SPI.
The multiplier starts getting mildly smaller at level 21, and get a bit smaller with each level that you pass. This way we want to make it harder to get medals (Especially gold & diamond) based on only a few games that you are very good at.

I have puzzled over the algorithm, but figured it was something like the first rule of SPI is do not talk about SPI.
I went up three levels in one game today - first level I got 14k for winning, second gave 2k, and third gave 6k. The one that gave me 14k I cleared on the first try. Did that affect my score? Who knows.
It is mysterious. But, it's been a fun and successful way for me to train my ears. :)

Gold was fairly easy to reach, but SPI-wise, reaching Diamond felt like climbing Himalaya 😂

Reading some comments I say : Come on guys don’t be lame, work hard and you will make it. The harder it gets the less you are rewarded with points, but nevermind. Diamond ears is a milestone but definitely not a perfect ear arrival line... keep on working, keep on learning and mostly keep on making music, so you will get good 👊

Thank you Noam.
