You were also “just lucky” before you admitted to cheating. Nobody is buying this. You‘ve cheated in the past by suddenly getting new sub-10 PBs every day, then you stopped for awhile, and now the cycle is repeating. The only way for you to fix this is to provide evidence at this point.
Dishonesty with times only impacts oneself, both through not knowing where they stand performace-wise, and also through mistrust by the community. I’ve said this before, but this is a very supportive group of people who will respect you if you begin to provide evidence or simply tell the truth. Even if your times are slower than you say, people will not judge you for that. You’re not gaining positive attention through this inconsistency and your past behavior. I have seen cases where people who cheat do regain trust through admitting the truth and providing evidence, and I promise that.
Everybody else also works extremely hard over the course of months and years to improve. Through our collective experiences, we understand what reasonable progress actually looks like, and this is not it. If you are being honest about the extreme improvements in times you’ve shown us, then I congratulate you on your WR in advance.
