Hi Ron,
Yes, I can assist with confirming the results obtained in the re-calculation. Are you implementing FCCM mode? and please confirm you have a proper feedback loop and connection for stable output voltage result.
In your initial post, you mentioned you changed couple components, were you able to replicate results similar to EVB 1V vout?
