I don't know how HoyoVerse's algorithm is, so I tried to create mine as realistic as possible with the following points based on in-game wish details. I also use GI Gacha Dataset as reference for wish probability.
if you feel luckier when you roll in this simulator, I can tell you it's just a feeling, In the simulator you can do a thousand or more rolls without limit, In real games your wishes are limited by the game currencies, therefore more chance to get multiple *5 item in this wish simulator

Probability for *4 item
- 4* Item guaranteed at 10 roll and promoted *4 item guaranteed at 20 roll.
- Probability to get *4 item is 5.1%, at pity 9 the rate increased to 56.1% and at pity 10 or more, the rate is 100% (guaranteed)

When you guaranteed for *5 and *4 item at the same time, your next pull priority is *5 star item and *4 item will appear next at pity 11. For example: On Character Event Banner, you doesn't get *5 star item until pity 89 and your *4 pity is 9, So your next pull will looks like screenshot below.
