Instructor variety from a students viewpoint can be varied, as long as there is core consistency looked for and prompted by each instructor then the student can only benefit from the varied focus of each individual teaching style. We generally try to keep most students predominately with one or two core teachers, but towards solo some variety in styles can help round out the students learning. 'lll often swap myself out if I feel a student is struggling or to get a different viewpoint in some instances.
Students tend to look for rapid progress all through their training, and this seldom happens, remember we expect young drivers to do 100 logged hours minimum to drive, yet in an infinitely more complex environment we can see pilots solo in a quarter of this time. Flying progress shouldn't be rushed or pushed, the hurdles along the way will end up being your best lessons in many ways.
I was too young for my first solo in gliders many years ago so the pressure was off, I had nearly 15 instructors in 3 years and yes while I gelled with some more than others I can honestly say that I learnt something from every one of them. The harder ones often proved to be the better instructors but this wasn't evident till many years later.
Enjoy the journey, there will be times when you miss having him or her there in times to come!
