You should try to keep your pad as flat to the surface as possible to prevent uneven pressure on the pad which can and usually does lead to holograms.
I would agree with the above statement.
Anytime you can hold the pad flat to the surface you should hold the pad flat to the surface. There are sections of panels that the only way they can be buffed wit a larger pad is to hold the pad on edge at an angle.
Couple of tips,
Clean your pad often. Rotary buffers can remove a lot of paint quickly and this shows up as a residue on the face of your pad and this residue is usually gummy or caked-up and it will make controlling your pad more difficult. There's a way to use a terry cloth towel to clean your pad on the fly, I show this in all our classes but don't have a video of it.
Pad Washers work great too...
The
System 2000 Pad Washer is for the most part best at cleaning wool pads with rotary buffers and it does a great job! If you're going to do a lot of compounding with wool pads and rotary buffers you need a System 2000 Pad Washer.
The Grit Guard Pad Washer
Shrink your pad size down when you're first starting to learn the way of the rotary buffer, if you look at the pictures from this class I had most everyone practicing with flexible backing plates and 5.5" foam pads.

Larry loves the Flex PE14 with a 7.5" Wool Cutting Pad and a Solo Flexible Backing Plate
Frank in the two pictures below was actually very good with the rotary buffer, you could tell he's been using an RB for decade as he made it look so easy...
That's a Flexi-Foam 5" Backing Plate with a 5.5" Hydro-Tech Crimson Pad... I highly recommend flexible backing plates, especially if you're new to the rotary buffer.
Look for products with good lubricity. Some products buff easier than others, an example are the Optimum Hyper-Compound and Hyper-Polish also the Meguiar's M205, any of the Menzerna polishes, both the Wolfgang Twins and the Pinnacle Advanced Swirl Remover and Finishing Polish.
Lots of info in this thread...
New Flex PE14 - How to use ONLY a rotary buffer to finish out hologram free?
I show guys to hold the polisher close to their body as this way you have more leverage over the polisher, as soon as you start extending your arms you loose leverage.
