It all depends on what chart speaks to you and your style I suppose.

I don't know the formulas for RRG, but, a daily plot likely uses daily data and a weekly plot weekly data - so, for 30 days it would use 30 data points - while 6 weeks will use only 6 data points. Different numbers, different results. Also, weekly data is final only at the end of the week, so all data for six full weeks is from Fridays (normally). In other words, a full week is always Monday to Friday (excluding holidays), so if a week is not yet complete, (e.g. on Wednesday) you still get a plot but its not 30 days. Thirty days, on the other hand, is always 30 days.

So, when calculating the difference between the starting and ending prices, the start price for a weekly RRG will always be the Friday of the first week. But the start price for the 30 days might be the Monday, Tuesday or any other day of the week.
