You can always shoot me a pm. I’m not as busy as some of the full time blood sweat and tears authors who are putting more hours into one custom than I do for five.

Come to think of it, I’m not the greatest with tempo mapping either. Most (all) of my customs have had simple 4/4 signatures, and several had the exact same bpm throughout. But I suppose the majority of mainstream music has that. TMing definitely confused me when I first started about a year ago, but it always helps to have a song with a nice easy kick/snare setup. Think “Billie Jean” or “Another One Bites the Dust” where those waveforms will really be easy to find.

Good luck with charting. It can be very rewarding once you get past the first few hurdles. One of the things some people have a hard time swallowing: Your first custom is going to suck. You need to be able to accept criticism here. People are going to tell you that something you spent hours on is full of flaws and will need many more hours to make the proper corrections. This has caused countless up-and-coming authors to bail when they were told their work wasn’t very good. Having thin skin is fatal here.
