Correct values, GJ, well done. Although the marked value for R8 is 2M, so it's slightly out of its marked 10% tolerance.

The trick is understanding that a delta and a star (or 'wye' if you prefer) are equivalent. You can use my measured values very simply to work out the values of each arm of a star network, then use the "well-known" star to delta conversion.
