Part of the work I have to do for my degree is to perform a "Hohmann-like" transfer between Earth and Mercury, of which I believe I have accomplished. I have attempted numerous times to confirm that it is "Hohmann-like" with the Professor with no reply, which I find rather vague and my worst nightmare is to get to the Mission Summery presentation and find out it is not in fact "Hohmann-like".
A conformation would be a great relief.
Secondly, I done the transfer with both chemical thrusters and electrical. I expected that the Delta V of the electrical thruster would be significantly lower but apparently this was not the case. Shown below:

[I have gotten rid of a propagation sequence that I realised did nothing. This explains the difference in the image and the data]
This leaves me under the impression that I have done something wrong. What am I missing?
Thank you.
