Don't waste time testing.
If you think your FTP has gone up then it has. Trust your instinct.
If the training plan wants efforts as a % of FTP then use a new FTP. As said, as some point you've got to raise the power. So either longer efforts or same efforts at higher power to keep increasing load.
You're in a training block so tired, your FTP test now might be the same number as your last, but if bet that means your real FTP has gone up. As FTP is when rested and ready to smash it up, not during a block when tired. So plow on, trust your judgment and just keep increasing the load for training benefit.
