I need to understand the SR Variables

I wrote a general explainer here: How Competitive Skill Rating Works (Season 10)

What does SR gain/loss depend on? After a good 10 winning streak of 25 SR each game I took a break and then played another game later and lost 46 SR.

Either you made a mistake in your notes, or you ran into some funny business related to win streaks. Possibly this:

High win percentage debuff / Low win percentage buff

As mentioned, SR is pulled in the direction of MMR (22). There is evidence (29) that this leads to an unfortunate and unintended side effect: If SR is well above MMR because a player has won many more games than he’s lost, less SR than MMR will be gained on a win, and more SR than MMR will be lost on a loss. This is an SR debuff. At high win percentage, a player can gain up to 6 SR less on a win than he loses on a loss (29). The effect is expected to reverse at low win percentage (SR would be buffed). The effect goes away once a player’s win percentage gets near 50%. That is, the player’s MMR is not ruined for life.
