All im going to say is be very careful about using ideal ratios coz there all bs
unless the give u an industry average be careful of commenting on a figure becasue a lot of things quickly change what could be acceptable for a business
for example a Business A selling essential goods can take higher debt than a luxury good business becasue Business A will have more steady sales throughout the year
Eddy's prettymuch sport on with the 'ideal figures' but just make sure u justify why your using it, nad if possible dont use an ideal ratio unless they give you one.
Good luck Guys
