Just tossing ideas out here...

• Is the yield calculation to complex. Maybe the early staker bonuses are the problem. Possible fix, separate bots - 1 for base yield, one for bonus yield.
• Node fallback - I know you have 2 nodes now, plus LEO's, but most div bots for HE tokens we own seem to be working fine on public nodes - maybe they could be used until in house infra is running smooth.
• Spread timing - send each at different times of the day, so it's not too much all at once.

Dunno, I can't do any of this, so just tossing ideas around.

@askrafiki do you have any other suggestions for @leostrategy?
