That flying was all done with an instructor because I don't have the piggyback license
As you were/are not qualified to fly an N-Reg aircraft then none of your flying could be as PIC, and all of your flying has to have been logged as PUT.
As this was not with an EASA Instructor they are not entitled to sign you off for your Tailwheel Differences Training - so you are still not entitled to fly a Tailwheel aircraft; and none of the flying can count as the 1 hour Dual required for SEP Revalidation by Experience - as this also has to be done with an EASA Instructor.
