Thank you for asking & the opportunity! Personally I believe much can be learned from many & less. Observation at your profile there is a great beginning with opportunity. Congratulations! You have a great adventure before you – Learning, authoring, writing content & more. I believe curiosity is wise many times. Also, I am empathetic. At times much can be from many and less too.
My answer is, IMHO, proposed are two key elements with comparison. An Average Hub Score typically is 70. ‘Normal’ I feel varies & is individual centric. There is difference with focus too. I tend to be at that average with all my Hubs, but herein enter ‘normal for me’. There are two distinct categories with the Hub Score – Informational & Creative, with their criteria, (See Following). I have a higher historic average with my Creative Hubs.
Short Story: Once I wrote near 200 Hubs over 3 years. My focus changed. This year I took hiatus from writing. I also assessed and diagnosed my Hubs Score performances and traffic in both categories seeking discovery while continued reading. I decided to begin anew as is seen at my profile. (Subplot: Traffic is a New Topic to explore later seeking discoveries) A moral to this story may be discovering strengths then build on those while seeking & discovering more.
Personal sharing . . . how I am doing that with ‘my New adventure’ with my Hubs on the drawing board is focusing on the ideal Hub. However, I realize experience helps. Personally I have a tendency to over explain evidenced with hubs nearing 3000 words.
Discovered at the Learning Center an ideal Hub is "A 'minimum of 1150' words of truly informative, well-written, useful content". Those four elements I consider today while know there is prudence with each.

The ideal Hub is known as a 'Stellar Hub’ → https://hubpageshelp.com/content/Learning-Center-E... . . . that is used for the QAP process.
The two main categories – informational & Creative, have different scales for rating a Hub. They both focus on three main elements; Substance, Organization & Grammar / Mechanics → https://hubpages.com/help/hub_hop_table#informatio...
Hints: Editing a Hub after published offers incremental change. At times better may be a new Hub approach using the same topic & main elements offering a greater Initial Score.
Have fun, fun, fun . . . as best as can be :-)
