@Flatface777I just had a $299 negative balance report while attempting the AZEO method again & gained 8 points from my youngest account passing the year mark & a HP falling off.
The -$299 reported as $0 & only the $20 I let report on another card showed.
While you may have had a -$299 balance, it didn't "report" as negative balances do not get reported. You later stated that it reported as $0, so in terms of language I think it's important to reiterate here that negative balances don't report as negative.
8 points gained from AoYA hitting 12 months and an inquiry falling off is on the very low end. Most report a gain in the 15-20 point range for this.
Just so you are aware, simulators are highly unreliable and in most cases should be ignored. Never count on anything they tell you, as it often won't happen.
