Question about Complex Numbers Larger Real Impedance of Mean than Real Impedance of Channel

Hello,
I am not getting something conceptually. I have multiple sets of data in a cell structure. Each cell contains (freq, real admittance numbers, imag admittance numbers) for a channel.
To get the real impedacnce for a selected channel, I do
adm = real admittance + (1i* imag admittance);
imp=1./adm;
realimp = real(imp);
imagimp=imag(imp);
I plot all of these channels and the largest value I get is around 700ohms .When I go to calculate the mean real impedance, I use the loop below. When I plot the mean real impedance, I get a large number such as 4000 ohms. I think it is ok but want to double check: is it ok for the real impedance of a mean to have a value above the real impedance of a single channel?
num = length(handles.celldata1)
for index=1:num
m = handles.celldata1{1,index};
m1(:,1)=m(:,1:3)+m1(:,1:3);
end
%Divide the first three columns by number of options to get the mean
%admittance data.
m1 = m1/ num;
imped = 1./m1;
realimped = real(imped);
