Turboflakes Grade
era 9706
· captured 2026-06-25T22:18:36.799796
This grade does not affect your rewards or slashing risk.
It measures parachain-backing performance only - useful as a quality signal for nominators, not a financial penalty.
One or more signals slightly elevated - see explanations below.
Grade
B
● healthy
Explain
What this is. Turboflakes grades each para-validator per era. A para-validator is a validator picked by the relay chain each session to verify parachain blocks - assignment rotates so every active validator takes turns.
The 9 bands (best to worst): A+, A, B+, B, C+, C, D+, D, F. The grade is computed from your vote ratio (75%) and bitfield ratio (25%) - see MVR and BAR tiles for the inputs.
Yours: B - Solid performance - no action needed.
Calculated by Turboflakes from on-chain parachain backing data for era 9706.
MVR - Missed Vote Ratio
14.29%
▼ slightly elevated
Explain
What this is. When you back a parachain block as a para-validator, you cast one of three votes:
- Explicit - you ran the block yourself and signed off. (246 this era)
- Implicit - you trusted another validator's signed vote. (0 this era)
- Missed - you cast neither. (41 this era - these hurt your grade)
Formula filled with your numbers:
MVR = missed / (missed + implicit + explicit)
= 41 / (41 + 0 + 246)
= 14.29%
Bands:
- < 5% - excellent
- 5–10% - healthy
- 10–20% - slightly elevated
- > 20% - flagged with ✗ glyph by Turboflakes
Network median this era: 0.23%
- yours is
significantly above median - likely a node-side problem.
Likely causes (in order of frequency, with diagnostic commands):
- Node out-of-sync - even a few seconds behind misses votes. Check:
curl -s -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","method":"system_health","id":1}' localhost:9933
isSyncing must be false.
- CPU/disk under-resourced - para-validation runs WASM in ~2s. Check:
htop # sustained CPU > 80% on validator process is a red flag
iostat -x 1 # await > 20ms on the data disk is bad

BAR - Bitfield Availability
99.83%
▲ healthy
Explain
What this is. Separately from voting, every validator (not just para-validators) signs a small message each block - called a bitfield - declaring which parachain blocks they currently have the data for. This is how the network knows a parachain block is safe to finalise.
Formula filled with your numbers:
BAR = signed / (signed + missed)
= 2320 / (2320 + 4)
= 99.83%
Bands:
- > 99% - healthy
- 95–99% - mild lag, usually transient
- < 95% - node not keeping up with relay-chain block production
Calculated by Turboflakes from relay-chain block data for era 9706.
Para-validator inclusion:
66.7%
- fraction of sessions in this era when you were picked to back parachains.
Random rotation (every ~10 sessions on Polkadot) - informational, not a quality signal.

■ para-validator era
era 9706
Pattern:
drifting.
MVR varies a lot between eras - likely intermittent issues worth investigating.
Last 7 eras:
worsening - recent avg 8.11% vs prior 6.26% (Δ +1.85pp). Worth investigating recent changes (config, OS updates, hardware).
Network rank:
Bottom 30% by MVR in 27/28 eras - your node is below network norm.
Para-validator role:
picked in 28/28 eras
- this is rotation by the relay chain, not a quality signal. Eras where you weren't picked have no MVR/grade.
